Car is in color!!!!!!!!!!!!!

First off, I AM NO EXPERT! But I think my advice will be good anyway. First, every spray gun is different. Look at the sheet for the gun to see what pressure is needed. I use an old Devilbiss HVLP at work that requires 75 psi to work, 2.2 mm fluid tip. I also have a newer Binks Mach 1,1.4 mm fluid tip, that needs less than 65 psi to have no more than 10 psi out of the air cap for atomizing. Those two guns need a high cubic feet per minute, (CFM) rate from the air compressor to work. Something like 13 or more CFM. I bought some cheapo Coleman Powermate gun from a Menards near me on sale for $35. It has two guns, a 1.4 tip and a 0.8 for touchup. Real cheap guns, but I practiced with them to get the right finish. I got them also because they required a low CFM to work. I could not get a 220 volt compressor. I have a lot of fun at work, I get to watch paint flow out and dry. As much fun as watching grass grow. Nah, the paint is more fun. Hope your project works out for you!
