No problem on the cleaning of the air gun. If you want to get it really clean, totally disassemble and soak all parts (except any rubber or plastic) in a vat of MEK. As far as degreasing, I use some glue and adhevive remover that Wilsonart used to make. I have a couple of cases my dad got me when he worked there. It's already in a spray can and it gets EVERYTHING off. I wish I could get some more.
