[Glock 18]

What was the flash time you used between coats, you might have put a coat on top of undried paint, the top coat might be nice and dry but underneath will still be soft could be why your leaving fingerprints in the paint, also did you sand and treat it with a plastic primer/sealer? before priming/ painting you going to want to wipe it down with a nice degreaser. we used one called 3919 at the body shop i work for works amazing.
