Not sure what I'm doing wrong, but.... I have a Paashe VL, trying to spray various acrylics with zero luck. I've tried Tamiya, Pactra and Testors, and consistently get the same results--spitting, splatters and beading. The spitting and splatters I could normally attribute to thinning or air pressure, but I've adjusted both up and down to no avail (latest attempt was 2:1 paint/thinner and 10 PSI). Initially I was using the #1 tip/nozzle in the airbrush to keep the spray pattern small, had all the above problems, so I went to the #3 tip/nozzle, no change. As I thin the paint more, the beading becomes worse, and if I thin less, it spits and splatters. Now FWIW, I'm spraying onto washed and dry but unprimed surfaces--is that the problem? If so, what do I use for primer, and how do I not get buildup and lose surface detail? I've never seen Mr Surfacer in the local shops, so is there something else? I don't have these problems to this degree using solvent-based paint, so I can't blame it all on lack of talent/experience, although it's most definitely a factor. Also, the VL is my first and only airbrush to this point--a different one is not out of the question, so if anyone may have something they want to swap, I'm game. Painting full size stuff is so much simpler.
