I bumped up the pressure at the gun to 55psi. I shot a test pattern on the wall (w/masking papaer) until the pattern looked good. I then shot a coat of DPLF50 on a 2 ft sq. piece of sheet metal The material layed down better but still leaves a lot to be desired as far as smoothness. This isn't my first attempt at painting but iit is with the HVLP gun. In the past I have used my DeVilbiss JGA syphon feed. That gun is no longer functions. It has a leak somewhere. I tried to rebuild it and it didn't help. Finishmaster will send it out for me but I really want to use HVLP. I like the reduced overspray and it doesn't leave as much of a fog in the air. I will continue working with my gun but if I can't get it right, is the DeVilbiss Finishline a pretty good gun?
