My compressor is 6.5cfm @ 40psi, 5.5cfm @90psi.
So at 10 psi, it's probably a little higher. Is this at least borderline?
Also it seems to be hard to control the pressure way down by 10psi, or at least the guages suck. I had trouble getting the pressure right when doing ceiling knockdown texture, which is low pressure.
Should I add on a better pressure regulator?
You can get an inline regulator with gauge for $10. The affordable guns by Devilbiss (FinishLine) need 23 psi at the gun inlet to achieve the 10 psi at the nozzle.
If you're still talking about doing smaller jobs like your truck interior, you're good to go. Your tank is fine. The CFM talked about here is for continuous output by the compressor ( like if you held the spray gun on for many minutes). The only thing you may have to do on something as large as your truck is wait for the compressor to catch up. Heck, I've been painting small stuff for years with a 12 gal. tank and a gravity gun which uses more CFM.
If you want to play with a gravity gun, I'll lend you my older Sears gun that came with the compressor.
