I'm going to be purchasing and air compressor and I need to know what things I should look for. I'm looking at craftsmans, but I need to know what the baseline scfm @ 40 and 90 psi that I will need to use body work tools is. Thanks!

 

make sure the motor is 2 stage. I have a craftsman 2 stage 25 gal. works good but does need breaks to recharge from time to time. i use mine for body work too and have no complaints.

 

Look up the body tools on the net, or at Home Depot, or etc. Then compare them to air compressors. Check out http://www.northerntool.com for some big ones! Mine is a 5 HP single stage (120 volt) 20 Gallon Campbell-Hausfeld, and does okay with normal tools. The D/a sander usually drains my compressor fast when I use the sander at full throttle, but I've found the d/a is pretty effective at half-throttle. And the paint gun I bought (Devilbiss Finishline II HVLP) doesn't use much air at all (low SCFM @ low psi)- I haven't used the gun yet but according to the specs, I should be fine.
