If you want to paint an entire car at once, it’s not going happen with a small air compressor tank and your gun will strain. You’ll end up running out of air before finishing the job because there’s just not enough volume in one tank for both spraying non-stop around full size vehicle.
You can take a chance and paint the entire car at one shot if you are daring enough to listen for any pressure drops.
The smaller tank WILL get hot due to constantly running an air compressor giving off heat through its motor which usually builds up water from being used often – just be sure not only fill it back up after each use but also empty out all excess liquid when finished using the air compressor.
You can paint the car in steps (same day) with a smaller air compressor but you may run into problems with overspray on the clear coat stage. When laying clear on the car you want to spray it on at once because if you wait too long and spray you will make your other glossy clear panels dull from the overspray that you create. You have a certain time frame where overspray will just melt into fresh clear coat, which is what painting flash times are all about.
A 60 Gal tank with a 5-6 HP compressor is recommended to provide enough CFM for your spray gun. Look at models that range from 14 – 18 mph and 90 PSI of pressure.
So what does this all mean? We suggest picking your air compressor size by calculating how many cubic feet per minute (CFM) the average person uses on their tools. If you’re not an avid painter, then consider getting one with less output for painting jobs; however if that’s not enough and want some big time painting power at home – go ahead with more powerful unit.
And never forget: You can never have too much CFMs because growing into it will be easy as pie over time.
