No, but the ingersoll will struggle as well..

I think you're right. I found a HVLP spray gun set at my local automotive paint store and the cfm rating is 7-9 @15-45psi.

After all my research I think I am going to go with this one: Its a 2 stage; 80 Gallon. It has 15.8 fm @90.

The sale ends on 12/27. I can have it shipped from their site for $117 and I avoid Sales Tax.
