I need to get a compressor to do my own body work. Unfortunately, I do not have much room at all. My garage is a compact one I have at my appartment complex.

My plans are to do small body work jobs perhaps a fender or pannel at a time. With a good quality low pressure spray gun (speaking of which what is good to purchase in that respect). I was looking at some compact ones you could cary with one arm. The size was ideal. What ratings should I concern myself with? One ran a PSI of 150 and another 200 psi. What should I look for? I don't mind if the motor kicks in and out a lot just so long as the gun doesn't loose pressure on small jobs.

THanks!!!!
