I started this article with the idea of writing about paint overspray on cars and how to remove it.
Then it occurred to me that some car owners with this problem might want to know more details about paint overspray and how to deal with it beyond being told to get a buffer and a clay bar and go to work.
Sometimes you simply want to find the person that covered your car in hardened spray paint droplets and have them take responsibility. Most of the time it’s just an accident or mistake on their part and it’s the reason they have liability insurance coverage.
You also have insurance for a reason. And paint overspray removal is a very common issue that insurance companies frequently deal with. So much, in fact, that many insurance carriers have national contracts with paint overspray removal services and/or auto detailing shops for clay bar and buffing services.
Since this is AutoDetailGuide, we like to cover all aspects of an automotive topic. Like we’ve been doing since 1999. This article is generally the first step in starting the paint overspray removal process.
So let’s talk about how to remove overspray. From the basics like what it is and where it comes from, to the advanced topics of how to file an insurance claim to remove paint overspray, and how to make sure you aren’t out of pocket for the repair costs.
The word “overspray” refers to the phenomenon of droplets of paint or similar related coatings that are dispersed through the air but do not adhere to the surface it was supposed to cover. This is where the “over-spraying” aspect comes from.
Overspray is a surprisingly common occurrence in many industries, including automotive manufacturing, construction, and, of course, painting.
What is Spray Paint Overspray?
Spray paint overspray is what happens when paint is sprayed through a pressurized or airless sprayer and lands on a surface other than the one it was intended to cover. The most common example is latex paint or polyurethane sealers that are carried by the wind and land on something other than the intended surface. On windy days paint overspray is a serious problem. It could land on a car, truck, house, boat, or any number of objects.
What is the most common type of overspray?
The most common type of overspray is sprayed paint. Most often this is latex paint, but there are many others including epoxy deck stains, industrial epoxy coatings, and heated highway line paint.
Where Does Paint Overspray Come From?
There are many different types of overspray and they are usually named by the source of the coating in question. The most common examples of this are:
Highway line painting
Bridge painting projects
Residential home exterior painting
Cleaning wooden decks and applying polyurethane sealers
Each type of paint has a different chemical makeup and will require different removal methods.
Epoxy paint like those used in commercial paint jobs, bridge painting projects, painting water towers, and large office building painting, is some of the most difficult paint to remove. Anyone who has ever sprayed paint on anything will understand how fast paint spray travels. This is why you see the huge white tarp wrapped bridges for overspray prevention when you’re driving on the highway.
A painting contractor knows how difficult it is to remove industrial epoxy coatings from a painted surface. Applying paint that doesn’t come off is their job. It’s also their responsibility to prevent overspray to mitigate or reduce potential damage claims that are caused by their performance.
The surface that the paint is on will also play a role in what removal methods will work and also affects overspray removal prices.
For example, bridge painting projects use epoxy paint that is heated to high temperatures and then applied with spray guns onto the surface. Painters use many methods to prevent overspray, but sometimes it still escapes. Large commercial paint jobs drift in windy conditions like this. And that type of paint overspray removal is very difficult without damaging the underlying surface.
Highway line paint is another difficult type of epoxy paint to remove. It is also heated to high temperatures and then applied hot to the surface with spray guns. Highway road paint is designed to withstand harsh conditions, including weathering, UV rays, and road salt. The road paint workers do attempt to prevent overspray, but they have to use large spray patterns to get enough paint on the road.
If you’ve ever tried to attempt road paint removal from your car’s inner wheel wells, then you know how it’s difficult removing overspray like that.
So it stands to reason that removing it from your car is equally difficult. That’s why an auto insurance company will have insurance claims experts that deal with these types of claims.
What Causes Paint Overspray?
Overspray happens while painting anything. It can be caused by many things, from faulty spray painting equipment to weather conditions and carelessness on the part of the painter. And while it is more commonly associated with damaging car paint jobs, it can happen anytime a painter is working with paint.
There are a few factors that can contribute to overspray. The most common one is the use of an improper spray gun or nozzle. If the atomization of the paint is not correct, it can result in large droplets that spread out too much as they travel through the air.
Bad weather conditions can also cause the paint to dry too quickly or blow away in unintended directions when it’s windy.
Another common cause is not having proper containment around the work area. This could be something as simple as not tarping off a vehicle before painting it. If there is nothing to contain the paint, it will spread out and eventually land on something else.
How Far Does Paint Overspray Travel?
Paint overspray is carried away from the spray gun by the wind and can travel for miles. This is what causes it to land on cars, trucks, houses, and other surfaces that are not its intended target. The farther away from the source, the spray pattern, and the number of spray guns applying paint, the more widespread the damage will be.
This is why contractors are forced to pay so much for their liability insurance coverage. And why most go out of their way to prevent overspray from happening at all. A small accident can cover an entire vehicle, or just the windshield and plastic trim.
But a large claim can be tens of thousands of dollars or more.
How Does Paint Overspray Get on Cars?
There are many ways that paint overspray can get on cars. When paint or sealant is applied to a surface with a spray gun from an airless paint sprayer, some of it will inevitably fly off and land on other surfaces nearby. It turns into a fine mist of paint particles, so it is bound to travel some distance.
Common ways to get paint overspray on your car:
Driving through an area where a painter is working, even if you are several blocks away
Having your car parked near or under a structure that is being painted
Driving or parking near a construction site where workers are using paints or sealants
Driving or parking near a bridge that is being painted
Driving behind a highway paint truck sprayer
Driving or parking near a house having its porch deck boards painted and/or sealed
What Does Paint Overspray Look Like?
Clearcoat contamination and paint overspray are often missed when you are looking at your car. The problem is the size of the droplets and the color of the paint or sealant. Even black paint overspray on a white surface might look like a light dusting of dirt because it’s such a fine mist when it settles on your car.
The easiest method of identifying overspray is not through sight, it’s by touch. Run your hand over the car and feel the paint. Your normal car clear coat is perfectly smooth. But overspray feels bumpy, like sandpaper. If you feel something less than smooth, it’s a good indicator that you have paint overspray on your car.
Who is Responsible for Overspray?
Paint overspray damage is usually caused by painting contractors, auto body shops, bridge painters, construction companies, and so on. There are many types of businesses and contractors that paint.
And reputable businesses all have insurance. It protects both them and their customers.
Most contractor insurance policies include paint overspray coverage. This is because it is a common occurrence and can cause significant damage. The policy will cover any damages caused by the paint overspray, including:
Paint that has been deposited on the surface of the car
Paint that has been deposited on the windows or windshield
Paint that has been deposited on the paint job itself
Industrial bridge painters and construction companies pay a lot of money in liability insurance coverage to pay claims resulting from paint overspray damage.
So do painting contractors.
And when your neighbor admits he used a paint sprayer indoors but swears he left the windows closed? He has homeowners insurance just for that reason.
How to Verify Contractor Liability Insurance is Active
At a minimum, you should have proof of coverage or a certificate of insurance for your contractor’s liability insurance. This certificate allows you to see exactly what type of liability coverage the contractor maintains. And also verify that the policy is active and in force (paid and up to date).
You should also be listed as an additional named insured so it is easier for you to file a claim and verify coverage. Any contractor that has a problem with this part of the hiring process, should simply be avoided.
Does Contractor Liability Insurance Exclude Overspray Claims?
Short answer, no. Long answer, possibly. It really comes down to the contractor and which options they choose for their commercial insurance coverage.
All reputable contractors have liability insurance that is initially offered with overspray claims coverage included. If you’re concerned about the possibility of overspray damage, ask your contractor what kind of liability insurance coverage they have in place before you hire them.
Where you run into problems with this is with a professional painter that is trying to save money on their liability insurance costs. Many insurance companies now offer the option to exclude overspray coverage from their professional liability insurance policies. The cost savings can be significant, so this is an important question to ask your painter.
Keep in mind that any professional painter can still cover your neighborhood in overspray even if they don’t have overspray coverage. If that happens and your neighbors want their homes repainted or glass windows replaced, your homeowner’s insurance might be the only protection you have. You can always sue your painter, but if they couldn’t afford full liability coverage, there’s a good chance they won’t have anything to recover in a lawsuit.
If you switch roles and you need to remove paint overspray from the body paint on your car because of a contractor that painted your neighbor’s house, your homeowner’s insurance will likely cover the cost of repairs. But before you go that route, talk to your neighbor and ask if they got a copy of their contractor’s liability insurance information. Otherwise, you will most likely be stuck paying the deductible on your homeowner’s insurance policy.
No matter what the source, it’s important to have the overspray removed as soon as possible. The longer it sits, the harder it will be to remove.
If you think your car has been hit with overspray, take photos and contact your insurance company right away. They’ll work with a professional to get the paint removed quickly and efficiently.
Or take it to your local auto detailing shop and ask about clay bar services. They can usually get your paint back to normal in a day.
Will My Auto Insurance Cover Paint Overspray Damage?
Most instances of paint overspray removal are covered by auto insurance, regardless of who is at fault. The problem is with deductibles. The average deductible in the United States is $500. And overspray removal prices average roughly $500 for a mid-sized vehicle. So it’s worth it to find out who did the painting and attempt to get them to pay for it. Or give the information to your insurance agent or claims adjuster so they can go after the person who created the mess.
What Should I Do When I Find Paint Overspray on My Car?
In most cases, paint overspray is not a serious problem. It’s just a nuisance that can be easily removed with a little elbow grease and some cleaning supplies. However, in some instances, paint overspray can cause serious damage. For example, if it gets into the engine of a car, it can cause costly repairs.
And depending on the condition of your paint, you could be looking at a new paint job if the damage is extensive.
How Do I Identify the Type of Paint Overspray on My Car?
If you find paint overspray on your car, the first thing you should do is identify what type of paint it is. Once you know what type of paint it is, you can research the best way to remove it.
How do you identify the type of paint? Do some detective work.
If you have yellow highway paint in the wheel wells of your car, you probably drove behind a highway painting truck.
If you see tarps hanging from a bridge near your office and you have the same color paint as the bridge, you probably have overspray from the bridge contractors.
Is your neighbor boasting about his nice, shiny, newly cleaned, and sealed deck? And your car is covered in clear overspray bumps? Then you got hit with polyurethane deck sealant overspray.
In many cases, a simple soap and water solution will work to remove light or medium overspray from cars if you catch it quickly. However, if the overspray is more difficult to remove, you may need a stronger solution or specialized products.
Removing paint overspray can be a challenging and time-consuming task. But it’s important to take the time to do it right so that you don’t damage your car or cause further damage by using the wrong removal method.
Should I Consult a Professional Detailer or Body Shop to Remove Overspray?
If you’re not sure what type of paint overspray you have, or if you’re unsure of the best removal method, it’s always best to consult a professional. A professional detailer or body shop will be able to identify the type of paint and recommend the best way to remove it. They will also have the proper tools and products to get the job done right.
If you find yourself dealing with paint overspray, the best course of action is to remove it as soon as possible. The longer you wait, the harder it will be to remove.
If you’re ever faced with dealing with paint overspray, don’t panic. In most cases, it’s not a serious problem and can be easily resolved. And if you do experience any damage, don’t hesitate to file a claim with your insurance company. They’ll be more than happy to help.
Paint overspray generally concerns unintentionally applying paint or a similar coating to a surface that wasn’t the original target. In other words, you accidentally created a mist of paint spray that floated away and landed on nearby cars, houses, and buildings.
For obvious reasons, it’s not a great situation to be in if you are the person that created the overspray.
And for reference, even though I’m focusing on paint and related coatings, overspray can occur anytime you spray a liquid chemical in the air.
Where Does Paint Overspray Come From?
Unfortunately, it’s often left up to the owner of an overspray-damaged vehicle to channel their inner Sherlock Holmes and search out nearby clues as to the source of the paint overspray.
Sometimes it’s as easy as looking up to see a bridge or office building getting painted. A simple Google search will result in large numbers of paint overspray horror stories. Like the water tower painter who accidentally covered 900 cars in a wet droplet cloud of epoxy paint.
In those situations, one of the responsible parties will usually hire a paint overspray removal specialist to fix the car paint at your house or take it to their local detail shop or similar facility.
List of Common Sources of Paint Overspray
If you need some ideas on where to look, the following list is a good place to start. Just remember, on windy days paint overspray can travel a fairly good distance before drying and falling to the ground.
Bridge painting projects. Look for white tarp-wrapped bridges. They use industrial epoxy coatings that stick to anything.
Construction site and large office building painting. They also use epoxies that aren’t clearcoat-friendly. The wind up there moves fast.
Painting Water Towers. Most hold a million or more gallons and are hard to tarp for painting. Both the insides and outsides are painted with heavy zinc primer and two coats of epoxy paint.
Residential home exterior painting. Never underestimate the power of one painter with a spray gun. They can overspray an entire neighborhood in less than a few hours.
Wooden decks and porches. The double whammy of epoxy deck stains and polyurethane sealers. Looks like tree sap, but sticks to anything.
Tree Sap. If you see something that looks like hard, sticky syrup on your car, look above and you will most likely see the tree that caused it.
Road paint and highway line paint.Highway paint removal is so bad that we gave it a page of its own here on the ADG website. It’s called hot melt marking paint and it’s sprayed on roads after heating it to 392 degrees (Fahrenheit). Road paint removal is difficult but entirely possible to do as a DIY project at home.
Will My Auto Insurance Cover Paint Overspray Damage?
According to insurance claims experts, more than 1,000 vehicles a day are damaged with paint overspray, resulting in damage claims in excess of $500 million annually.
The problem with quoting statistics is that they don’t always give the full picture. If a professional painter causes overspray damage to your car, they are usually liable to pay for damages.
Usually? Well, there’s the little problem of actually getting paid. We have a similar article here on our site that goes into more detail on locating the source of the overspray and figuring out how to get them to pay for the costs of professional paint overspray removal. Check it out when you have some time.
Contractor Insurance That Excludes Overspray Claims
Liability insurance carriers, the people that cover contractors, are painfully aware of the costs involved with damage to car paint and clear coats from overspray.
That’s why liability insurance costs so much. And also why many painting contractors don’t carry liability coverage. It’s an expensive cost of doing business for any professional contractor. So naturally, some contractors let their policies lapse because they can’t afford the cost.
Insurance companies understand that cost is an issue. So to make these policies affordable, companies offer cut-rate discount contractor insurance. It makes sense for a painting contractor that only offers interior painting services to save money on their contractor liability insurance by choosing to exclude coverage for paint overspray claims. On the other hand, some painting contractors that do exterior painting might choose to exclude overspray coverage if they’ve never paid claims related to that type of damage.
The other issue is deductibles. Yet another way that liability insurance companies can reduce their exposure and offer lower rates is by setting a per-incident deductible. So that painting contractor that says they have overspray coverage, may in fact have a policy that sets per claim deductibles above $500. This means the painter will be paying out of pocket up to $500 per car.
Here is where I add the obvious disclaimers about how I’m not a lawyer and this isn’t legal advice. But it also doesn’t take a rocket scientist to figure out your chances of recovering that money might be difficult. Either way, you should always consult with your auto insurance carrier and your lawyer.
Insurance Deductibles and Overspray Damage
Now let’s talk about your side of the equation as the victim of this overspray problem.
And most overspray removal service bills come in at less than $500, depending on the extent of paint damage and how much work is involved.
Regardless of how much money it costs, it is always frustrating being forced to pay for damage to your car paint that is caused by a “professional” contractor. Any professional should know how to properly do their job.
This is why I mentioned above about speaking with a good lawyer about your claim. They might have ideas for possible ways to mitigate your out-of-pocket costs and recover your money from the contractor.
Don’t give up if you run into roadblocks. It’s your money, fight for it!
How Much Does it Cost to Remove Paint Overspray?
The typical cost to remove paint overspray from a vehicle ranges in price from a low of $150 to a high of $500 or more. These rates are standard for professional detailers or reconditioning techs.
To clarify a few things, the price you pay will greatly depend on the size of the vehicle, the severity of the overspray damage, and where it’s located on the vehicle.
For example, is it just the windshield or is it covering the entire vehicle? And if it’s everywhere, is it a Kia compact or a Yukon Denali XL SUV? Obviously, the price points will be wildly different depending on those types of differences.
Another criteria that often affects overspray removal prices, is the type of surface. Removing paint overspray from glass windows is measurably less difficult than removing it from body paint or plastic trim.
DIY Paint Overspray Removal
So up to this point, as far as paint overspray is concerned, I’ve covered what it is, how it happens, who is responsible to fix it, and ways you might be able to get reimbursed for your out-of-pocket costs.
If you exhausted all of those options and you are paying for paint overspray removal out of your own pocket, then you might be interested in fixing the problem on your own.
Let me just point out, upfront, DIY paint overspray removal is absolutely something you CAN try at home. A lot of people think it’s something only professionals can handle, but it’s not.
And it’s definitely NOT expensive. But as I will cover in the next section, paint overspray removal is very hard work. And you must be careful or you could end up destroying your car paint.
Is It Hard Work to Remove Overspray from Cars?
Yes, paint overspray removal is very hard work. That’s why detailers charge so much to remove it. And by hard, I mean labor-intensive. Not like back-breaking work moving a truckload of concrete blocks to your backyard.
DIY paint overspray removal is more on the level of setting aside a bunch of hours to take a clay bar and rub it on the outside of your car. And wash it. And rubbing it more. And washing it.
Clay on. Wash off. Clay on. Wash off. Very good Danielson.
Wax On. Wax Off.
Speaking of Mr. Miyagi. Removing overspray is one of those things that takes a frustrating amount of time to complete. Mainly because every time you think you’re done, you find some more.
Each time you dry your car after washing it, run your hands over the car again and try to feel for the tiny bumps of hard overspray paint droplets.
When you feel the paint bumps, you do that area over again.
And you will find some. Again. And Again. It’s frustrating how there are always a few that you miss.
Then you keep doing it all over again. And again. And again…
Wax On. Wax Off.
Disclaimer: I am obviously not Mr. Miyagi. I’m good, but not that good. So no, you won’t mysteriously know blackbelt level karate after you are done following my instructions for removing overspray from your vehicle.
You will, however, be as sore as I imagine Danielson was after he spent all day waxing all those cars for Mr. Miyagi.
Step by Step Paint Overspray Removal Instructions
If you are ready to get started, I have included a step-by-step instruction list for removing paint overspray from your car.
So let’s go!
First, a quick note. If you have any corrosive damage to your paint from environmental causes, paint overspray removal processes like the following will most likely not repair that type of damage. This is for the removal of hard droplets of dried paint overspray on your car exterior.
What are the environmental causes of corrosive paint damage?
Since I brought up environmental causes of corrosive paint damage, let’s briefly discuss this so you know the difference going into this.
Paint corrosion problems caused by the environment have been in the news for decades. These are issues like acid rain, toxic industrial exhaust or plant discharge, even bird crap that’s sat on your paint for too long.
It’s all toxic to paint.
These environmental conditions can eat away at your car’s clear coat and paint. It’s fixable, so don’t think you need to repaint the entire vehicle. That’s usually not the case.
Many auto paint repair and reconditioning services can fix those problems without the need for a body shop.
But the tips I’m including here in these instructions, like clay bars and high-speed buffing, usually won’t fix corrosive damage problems.
So now that we are on the same page, let’s get started.
Wash Your Car with a Pressure Washer
The first step in the overspray removal process is to scrub your car. With soap. But the more important part of this step is to use a pressure washer during the entire wash process. Even the self-service car washes with the bays sometimes have enough pressure for this step.
Can I Use a Pressure Washer to Remove Paint Overspray?
Well, yes and no. Using a pressure washer while removing paint overspray is effective in blowing off or loosening droplets of overspray that were somewhat dry when they landed on your vehicle. Even though these droplets are still attached to your car, the bond with the clear coat isn’t always strong. Especially if you were quick to fix the overspray damage.
So yes, using a pressure washer will sometimes remove a significant portion of the overspray droplets from your car.
Especially if it was a long-distance that the paint droplets traveled in the air from the paint sprayer nozzle to your car.
The longer the distance traveled, the drier the droplet when it lands on your car. Ultimately, that results in a bond with the car clearcoat that isn’t as strong as fully wet droplets.
So always start with a good wash and always use a pressure washer.
How to use a Clay Bar on Car Clear Coat
When it comes to painting overspray removal you need to start with a good clay bar. Detailer’s clay, as it’s called, is a special mix of clay that works incredibly well at removing impurities from your paint.
But how do you use a clay bar to clean a car clear coat? It’s a simple enough system. You take the detailers clay and wet it. You are also going to need some form of lubricant for the car paint surface. This is always a subject of debate whether you need special lubricants or not.
Some detailers will tell you that you need to use everything from spray-on finish wax to showroom shine products to keep the clay lubricated.
From my experience, a simple solution of Joy dishwashing detergent works great.
Your goal is to keep the clay bar lubricated as you rub it across the clear coat in a circular pattern. So whether it’s spray-on finish wax or dishwashing detergent, both will work.
Detailer Clay Bar and Lubrication
It’s a one, two process. Rub the clay in circles and keep following behind it occasionally with your other hand to feel for the dry bumps that overspray creates.
Keep going over it with the detailer’s clay until it’s gone, lubricating your work area as needed. Also, keep rinsing the areas you have completed, so you don’t let the clay dry as you are moving forward on the vehicle.
Another cool feature of clay is if you have already waxed the car, the clay bar won’t remove the wax on the painted surface, but it will remove the overspray.
Always Use the Clean Side of a Clay Bar
Something else to keep in mind while you are using the clay is that you need to keep folding it back into itself while you are rubbing it.
The clay will start getting dirty as it’s pulling everything off the painted surface of the car. So keep folding it over on itself, and you will always have a clean surface.
Eventually, the clay will need to be replaced, but one bar will do many, many cars. If you are doing this at your home, that one container of clay will last you a long time.
Another thing to keep in mind. Always keep the clay wet. It should come in a bottle with a replaceable cap. Fill the jar or container with your water and Joy detergent solution and put the cap on tight before you put it away after using it. This will keep it ready for the next time you need it.
After you have completed the entire car, you will want to wash the vehicle using your standard car wash soap mix with a soft wool wash mitt.
Once it is dry, you will be able to feel for any areas that you missed.
Can I Remove Paint Overspray with a High-Speed Buffer?
Short answer, no you should not remove paint overspray from your car paint or clear coat with a high-speed buffer.
Is it possible? Sure. But even after I spent a decade becoming an expert wheelman with a high-speed buffer, I still limited the situations where I needed to use one. The reason was simple. High-speed buffing can damage car paint and clear coats. The longer you use it on the car, the higher the chance for burnt or damaged paint.
When I was first learning how to use a buffer, we had an old car door we practiced on in our shop. I burnt straight through the paint to the metal on my first time. It was practice, so it didn’t matter much. But it was scary how easy it was to do that.
And burnt paint is just one of the many possible things that can go wrong with high-speed buffing. Spend too much time with a buffer on car paint and you are just asking for burnt paint, ripped molding, damaged accessories, and so many other possible and exciting ways you can damage a car.
Take my advice that I give to everyone that asks about high-speed buffer. Get an orbital buffer. My favorite for the past two decades is the Porter-Cable High-Speed Orbital Buffer. It’s a variable high-speed orbital buffer. The orbital aspect is what I love about it since it all but eliminates the chances of both burning paint and the clear coat swirl makes that a lot of buffers leave in dark color cars.
Nano Ceramic Coating or Polymer Sealant After Clay Bar
A car that has been through the clay bar cleaning followed by either high-speed buffing or orbital buffed to remove any swirls looks absolutely incredible. Apply a nice coat of Nano-Ceramic Coating or a Polymer Sealant to the paint after you are done, and your car will be ready for six months until you need to reapply. Personally, I love the Hydro Slick Ceramic Coating Hydrowax from Chemical Guys. It makes your car clear coat incredibly smooth.
The paint overspray removal process is not an easy one, but it looks great once it’s done.
When it comes to my preferences for detailers clay, I tend to stick with Meguiar’s brand detailing products. They have a Meguiar’s C-2000 Professional Detailing Clay which is a great product. These clay bars do a fantastic job of paint overspray removal. Highway paint, tree sap removal, and more.
Over the past two decades, I have used hundreds of bars of detailer’s clay. Meguiar’s and Griots are the best clay bars I have used, but my personal preference is Meguiar’s. I just really like the feel of their clay bar in my hand when I’m working it over the car paint surface.
