We've media blasted the door hinges, latch's, brackets, etc, and I want to primer them before installation. I'm waaay out of date with paint products so would like some input on what you guys are using these days. I have spray guns--both internal and external mix, as well as hvlp. I know the primer should be compatible with the finish to be used, so another question is ; what type of paint are you guys using ? My last spray job was with acrylic laquer back in the late '70's. I think the EPA has outlawed what I'm used to.
