I can't make myself use my $400 gun for polyester topcoat so I do get a few fish eyes in that. FWIW UH I know guys that are serious about painting are particular about what goes through their guns -- never put primer through their favorite gun and so on. But what's the rationale for this? It seems to me that the paint follows such a short path through the gun that it can't cause any serious wear. At least for gravity feed guns. Are there other issues? Jim Beckman The gun I use for AU has a smaller tip than the one I use for thicker filler. This makes it a bit easier to get a better pattern to atomize better which is less of a factor with spray filler. It is also a bit harder to get perfectly clean so I just switch guns. With filler I'm trying to put on a lot of stuff quickly. With finish coats, I'm trying for better finish quality. UH |
