Painting or waxing a car takes more precise application of primer, paint and top coatings than many other painting jobs.
To get the paint or wax applied evenly without drips is best done with the aid of an air compressor. Not all air compressors are appropriate for the job. A key factor to look for in finding the best air compressor for auto body work is the CFM, or cubic feet per meter.
Portability weighs into the choice as it is best to be able to move the compressor around rather than possibly have a hose drag across a freshly painted or waxed surface.
To get the best quality job, we will look at three of the best machines suitable for auto body work. These will include the DeWalt D55146 Hand Carry Compressor, the California Air Tools 5510SE Air Compressor and the Porter-Cable PCFP02003 Pancake Compressor.
DeWalt D55146 Hand Carry Compressor
This DEWALT D55146 Air Compressor isn’t designed for painting cars from the bare metal to fully finished but it is great for waxing and painting small spots to restore a car to looking its best.
At 90 PSI, it will give a CFM of 5 and has a 4 ½ gallon capacity for paint.
The DeWalt D55146 is easy to carry though it is made of steel, which makes it very durable. The valves and gauges connect quickly so you can get started with it very quickly. The machine is designed so it can be operated either laying flat or stood up vertically.
- Runs very quiet at only 79 decibels. It is possible to have a conversation even while standing next to it.
- It has a quick recovery time so jobs go much faster since little time is spent waiting on the compressor to recover.
- Compact and light enough to be carried easily.
- Some users have reported leaks developing.
- The plastic grommets used tend to break. Same with other plastic parts.

Our view on this DeWalt D55146 Air Compressor
It is fine for light work, such as waxing and touch up painting. If this is all you need an air compressor for, this one could work well for you.
California Air Tools CAT-5510SE Air Compressor
This is a popular choice of air compressor for all types of painting and waxing jobs because it works at a PSI low enough to put paint or wax where it needs to be without so much of it going into the surrounding air.
The fact it is oil free means it needs less maintenance. The 5 ½ gallon capacity allows you to keep spraying longer rather than stopping to let the tank fill again.
Up to 120 PSI can be delivered with this 1 HP air compressor and it can continuously run for quite a while due to the increase of the duty cycle.
You will get 3.10 CFM when the compressor is running at 40 PSI. At 90 PSI, you will get 2.20 CFM. Your paint or wax will go on evenly and smoothly with this air compressor.
As you will likely be working in an enclosed space to avoid getting debris on the fresh paint or wax, you will want a compressor that operates as quietly as possible. This air compressor will do that as it is built to be ultra quiet.
- At 60 decibels, this is one of the quietest air compressors around.
- The pump is maintenance free.
- The increased duty cycle allows the machine to run longer at a time.
- The large tanks allow it to operate smoothly.
Not much in the way of cons but a slow leak that some have reported.

- Easy to move from one place to another because of the light weight.
- The oil-free pump doesn’t need maintenance.
- Recovers quickly and can be run for a long time.

Is The Porter Cable PCFP02003 Air Compressor a top choice in our view?
If you need an air compressor light enough to carry easily, this one is worth considering. It seems to be better suited to spot painting and waxing a car than a from-scratch complete paint job. If this is all you need it for, it will be fine.
Our Final Pick
When considering which air compressor is the best air compressor for auto body work, we have to recommend the California Air Tools 5510SE Air Compressor as it will do everything in the way of auto body work while the other two are more for the smaller jobs.
Of course, it all depends on just what your needs are. If you are doing a complete paint job, including the finish top coat, The California Air Tools air compressor is definitely for you but if you just need it for detailing, spot painting and waxing your car, either of the other two will work just fine.
