I'm shopping for compressors as my old Coleman is pretty weak. It used to keep up with a DA sander but those days are about over. I was looking at one that puts out 7.1 cfm@40psi and 5.5 cfm@90 psi. Do you think that's adequate for painting a car? I have no idea what the specs were on my old one; it was an oilless 4HP motor with an 11 gallon tank and the one I'm looking at is belt driven with a 2HP motor and a 24 gallon tank.
