Is my compressor big enough?
I'm doing a little bit of bodywork to my F150. The bedsides and rocker areas need to be painted. Just wondering if my compessor would handle a spray gun or should I leave it for a shop to do.
Compressor: 20 gal, 2hp, 2 cyl. 7.5 cfm @90psi
Any opinions?
I'm thinking it's probably not up to the task.

Just doing a little more searching. Could I use something like this?

My compressor says 9 scfm@40psi
Wouldn't it be able to keep up if I went slow?
I'm really trying to stay away from having to use a lacquer touch up paint on this truck. If I end up having it painted later on when I can afford it, I'll have to have that all stripped.

I'd think it would be OK unless you're running a really big HVLP gun. I've run a vintage DeVilbiss and a Taiwanese touch-up gun off a home-built compressor that's about 2 cfm (1/2 real Hp). The touch-up gun might be a little slow for doing a bed side, but it should still be way faster than taking it to a shop and waiting for them to get around to it.
Here's a gun that only needs 5 cfm: http://www.harborfreight.com/cpi/cta...emnumber=91009
Adding a tank would give you a little longer spraying time if your compressor pump CFM is much too low, but then you'd be waiting longer for it to pump up again.
