I am attempting to paint a headlight and grill shell using PPG Duracryl DDC Acrylic Lacquer. The reducer the paint shop sold me is Duracryl DTL 876. I had problems with my old gun Saturday so I went to Harbor Freight and bought a HVLP gravity feed gun. My problem is finding the right combination of air pressure, paint viscosity, mix, etc. The best air pressure I've found so far is 35 lbs and I just kept thinning the lacquer so my final viscosity is unknown. The finish is "pebbly" to the touch. It wet sands down but it's just not right. Any advise will be appreciated
