Can You Spray Auto Paint With An Airless Sprayer?

Yes, it is possible to spray auto paint with an airless sprayer, however, painting a car with an airless sprayer may require a lot of effort.

This is because a lot of these sprayers may not be able to produce a finely atomized mist, which can result in a coarse finish on your car.

However, this can be corrected by thinning the paint with more reducers and applying more coats.

So while it is possible, painting a car using an airless sprayer can prove to be a pretty tough task. And to make things easier for you, we’ve made a quick guide to painting your car using a paint sprayer!

Read on to learn more.



Can You Use An Airless Sprayer To Paint A Car?

As we mentioned earlier, it is completely possible to paint your car using an airless sprayer, but it won’t be an easy task. To obtain the glass-smooth finish that you’ll commonly see on most modern cars, the sprayer needs to produce a finely atomized mist of paint, which isn’t something a lot of airless sprayers can do.

That being said, it is possible to thin the auto paint further with a reducer so that the sprayer can achieve the right mist, but this will also require you to put more coats.

On top of that, most car enthusiasts will tell you that the “painting” aspect is the easiest part and what is more important when it comes to achieving a clean finish is to properly prep the car and apply the right base coats and primer.

So if you’re comfortable using an airless sprayer and don’t mind having to apply more coats, then you should have no problem using it to paint your car, just be ready to do a whole lot of work!


What Kind Of Sprayer Can Be Used To Paint A Car?

So if airless sprayers aren’t the best tools for painting a car, what is?

Well, the answer to that would depend on who you ask, but a lot of people would recommend using an electric HVLP sprayer for painting your car.

HVLP stands for high volume, low pressure, meaning the sprayer uses high pressure air from a compressor and converts it to a lower pressure, which results in a spray with lower volume of paint.

This will reduce the chances of overspray which also reduces the cost of painting and the time it will take. Additionally, these tools create a finely atomized mist which is ideal for spraying auto-paint onto cars, as long as it is prepared properly.

On top of that, there are HVLP paint sprayers out there on the market that are specifically designed and made for painting cars.

This will ensure that you have just the right pressure and mist to apply clean and smooth finishes on your car that will last you a long time.

But remember, painting is considered the easiest part of these DIY projects, and what is more important is that you prepare your car for a paint job properly, making sure to remove any rust dents, and trim and also making sure to sand and prime the body before you start painting.

By doing this, you will have a much easier time later on getting that nice, smooth finish that you see on most modern cars.

What Are The Steps To Painting A Car Yourself?

Step 1: Prep The Car & Your Painting Area

First you’re going to have to find a nice wide space that you can paint your car in, preferably an area with electricity, one that is clean, and one with good ventilation.

Once you have the right spot, you have to start prepping the car for the project. This includes removing dents, rust, and trim and making sure the body is in proper shape for repainting.

Step 2: Sanding & Priming

The next step is to sand & prime the car.

To start, you will have to sand the body in a circular motion to get a smooth surface that the paint can adhere to. You can either sand all the way down to the metal, to the first coat of primer, or just until the surface is smooth enough for your paint.

From there, you will have to thoroughly clean the body using a rag and denatured alcohol to remove any oil and other residue that has been left on the body.

After that, you will have to tape up the surfaces you don’t want painted such as the windows, mirrors, and door handles.

Once that is completed, you can start priming. If you choose to sand it down to the bare metal, it’s recommended to use a corrosion-resistant and self-etching primer.

After applying the primer, sand it once again then wipe the surface down with a rag and thinner. Also, make sure to allow the primer to cure properly before proceeding to the next steps.

Step 3: Painting

Now that all the prep is done, you can now start painting.

Using your paint sprayer, simply paint the surface using a side-to-side sweeping motion, always making sure to keep the sprayer at least 6 inches away from the surface you’re painting.

It will typically take up to 3 or 4 coats to get a nice finish and you have to make sure that the first coats are properly dry before adding the next one. Different brands have different drying times, so make sure to check the manufacturer’s instructions.

Before applying the last coat, make sure to sand and wipe the surfaces again before applying lacquer using the same technique as you did when painting. From there, all you have to do is remove the tape, buff the car, and clean your workspace and you’re good to go!


So there you have it, a quick and easy guide to painting your car using an airless sprayer! It can be done, but it is a pretty tough task. But after all, painting your car by yourself is always going to be a project that requires a lot of time and effort.

Just make sure to follow the steps properly, use the right paint, the right equipment, and to choose the right workspace and you’ll be starting on your first DIY paint job in no time!
