Every car owner, or at least most car owners, knows that it’s vital to keep their vehicle well maintained. This ensures that your vehicle looks and feels nice.

At some point, you may have also thought about getting it painted, but without spending a ton of cash. It could mean a color change or a damage coverup. 

Check out what we uncovered when responding to the question “Can you paint a car with a 30-gallon air compressor?”.

As a general rule, most cars can be painted using a 30-gallon air compressor. In fact, the most important thing when choosing a compressor for painting is not the tank size but the CFM rating. 

You need to compare the CFM on he the air compressor to the paint gun that you plan to use. The CFM should be adequate enough to provide you with a high enough air output to do the job. 

How Many CFM Do You Need For Spray Painting?

Okay, so this is a question that gets asked a lot, “How many CFM do I need for spray painting my car?”. Not everybody knows that the air compressor needs to supply enough CFM to the spray gun to achieve maximum and consistent performance. 

Spray guns can require anywhere from 3 CFM and up. You can find spray guns that have a 3 CFM rating at 22 PSI for around $100.

This is plenty of power to spray paint your car. You can also purchase more expensive spray guns that are rated for 6.5 CFM at 90 PSI, but this will require a specific nozzle for a wider range if you’re doing a big project.

Painting Cars With An Air Compressor

To properly paint a car with a 30-gallon air compressor, you should first understand the three stages of the process. The first stage is the initial phase, the second is the preparation of an air compressor, and the third is painting & cleanup. 

Preparing Your Compressor For Car Painting

Before you do anything, you will need to prepare your air compressor, which is the easiest step of them all.

Simply turn on the compressor and let the air build-up. You will then need to ensure proper pressure regulation to match the specifications of the paint gun. Next, connect the sprayer to the hose through the couplings. 

If you need assistance fixing your hose through the couplings, here’s how you do it: 

  • Pour the thinner on the spraying cup
  • Unlock the metering valve lightly
  • Squeeze the trigger while the nozzle is turned towards a trash can for testing
  • You will hear air then the thinner will disperse
  • If you have succeeded in these steps, you can pour the remaining thinner into the cup

Step1: Initial Stage

The first stage is the initial stage. Within this stage, you will be choosing the paint and thinner, preparing the area, obtaining the proper PPE, and purchasing a primer.

You add the thinner to the paint to help it better move through the siphon tube and nozzle without an issue.

This part of the process ensures the environment that you’re painting will be clean and neat after the painting is done. So it’s important to cover the floor. 

You should also protect the painting surface from over-spraying by using masking tape and a magazine. You can also put up a barrier around the surrounding area that will keep the paint from transferring to objects around the vehicle. 

Additionally, you will need the proper personal protective equipment. The reason for this is because the paint is harmful to your health.

There are fumes in the paint that can essentially destroy your respiratory system and also cause skin diseases. The proper equipment needed are respirators, gloves, safety glasses, and a mask. You will need it when you paint, sand, and remove the rust from the vehicle. 

Lastly, apply the primer if it’s needed. 

Step 2: Painting

This is the most important stage. You will begin by first mixing enough paint for your car and placing it in a clean container.

Then add the correct amount of thinner to make the paint viscous. You can then add the mixer to the cup to ⅔ level and close it. Firmly grasp it before pressing the trigger as it can have a bit of a kickback. 

You can begin painting by pressing the trigger. You will want to hit the car with the paint at an almost parallel angle, not 90 degrees.

Try to keep yourself off the drips that come from the gun and overlap each pass to make the layers thick enough. Don’t stop painting while there’s paint in the cup. If you need a break, remove the cup. 

When you’re done painting, let it dry. If a recoat is needed, you may do so. A recoat is an ideal option as it will make the surface paint last longer. 

Step 3: Cleanup

This is the last stage and it ensures a super clean environment. You should return all paint to the original container and remove the tape you applied before the paint dries.

If it’s dry when you remove it, it could peel the paint with it and it will also be much more difficult to peel. If paint drops in the working area, clean it up as soon as you can. 

Conclusion

We hope that you found this article informative and helpful. As you can see, you absolutely can spray paint a car with a 30-gallon air compressor. Most air compressors of this size have enough CFM and PSI to provide to your paint sprayer. 

You may see that most people say you can’t paint your whole car unless you have an air compressor that provides you with over 20 CFM.

This is true to a certain extent. The higher CFM and larger spray gun will allow you to paint your car quicker, but you can still paint your whole vehicle with a smaller spray gun. The 30-gallon compressor and spray gun with a 3 CFM rating or higher will suffice just fine.
