i have used he HF guns and it needs 40 psi and a thinner mix to get a good paint going. I paint and just light sand between coats or dont sand at all. I am painting without a booth so a little dirt and maybe a bug or two will get in the paint. If you can use a down draft booth that helps imensly. look at the devill biss starting line gun set. I just upgraded to that and it uses the pressure it says it should. the HF gun will orange peel no matter what you do or it will speckle. great for $12 bucks but only good enough for farm trucks or trailers or equipment. the starting line kit is 150 I think two guns three tips and needles.
