PSI question

[jasedude]

Hi everyone, Ive been restoring a 1985 Pontiac fiero and it's time for paint! I got a quart of primer and quart of brilliant silver to test on a small panel before i paint the entire car. My dad got a HVLP gun a year or two back to paint his truck and it worked for him, so Imtrying my hand now, but this time with the paint shop system.

My question is concerning the PSI. First off, I noticed on the tank for the paint gun it says pressure should not exceed 10 PSI, even though Ive read that PSI should be anywhere from 20-35 PSI when painting with Paint Shop. Additionally, Ive read that pressure at the inlet should be at 90 PSI. The regulator on my tank only goes to 25. So when I tested it out today the paint came out all clumpy...kind of an extreme orange peel. I'm guessing this is just because I don't have the PSI right. What should I set everything to?

Oh yeah, the gun is a CENTRAL PNEUMATIC 5726 HVLP

Some guns have a regulator on the back side of the gun. I know that our Sata does. This means you can have 90psi at the inlet(hose) and then regulate at the gun(trigger). If not we specify about 15-25psi on HVLP guns. Spraying a test panel is the best practice so keep that up. Since each gun is different all I can suggest is keep testing until you get your desired results. If you are getting extreme orange peel try backing off your psi. It sounds like the paint is coming out with such force that it is drying before it hits the surface. Also try holding the gun closer. If you hold it too far back it will get course.

Make sure you mix the crap out of the brilliant silver every time before you pour it. It has alot of metallic in it and has a tendency to build up in the bottom of the can.
