I'm shopping for a Compressor to Paint cars with. I'm looking in the local advertisements. Maybe 3 paint jobs a year, intended use by me just a d.i.y"er.. My Grandma is old school and says I'm fine with a small hot dog compressor but all on the internet they say to get a 50/60 gallon/ 5hp. I believe my Grandpa is telling me this because he used to Paint with the old paint guns with the cup on the bottom. Anyway what should I be looking at? Cast iron/ or not? Oil-less? Single cylinder or double? I have gotten some guys down to 200$ for their compressors.. These are my choices with my budget. 1st is a campbell hausfled pictured in the 1st and 4th pic. It has 2 cylinders unknown cfm 7hp. 60 gallons. The 2nd is a Husky (but I think CH makes them) 6.5hp.60gallons 11.7cfm @ 40. and 10.3 cfm @ 90. BUT the guy said he's missing the "power box" (the box that covers the connections). 2nd picture. The 3rd is a campbell hausfeld in the 3rd picture. The guy says it's a 6.5hp, 60 gallon,210volt. Unknown cfm rating . Thanks for viewing my post.
