Jim,

I had my air compressor's regulator set at 60lbs but had the gun's regulator at around 40lbs. I also documented each knob setting on my gun so I can always check before each painting session.

Edwin,

I'll be honest and say that no I didn't filter the paint mix even though I have some in my garage. I did use distilled water and made sure the cup I was mixing the paint in was clean
