I have been considering tackling my first paint job on my 54 (after a lot of repairs). Now my confidence is starting to fade. Who new paint was such a science? Ambient temps, substrate temps, length of the air hose, dryers, filters, "oh my".
I hadn't painted a vehicle since the '60's when I started on my current project. Got epoxy from NAPA (Martin Senour PIP302) and got good results from that (FOLLOWING THE INSTRUCTION SHEET). And PPG ALK-200 finish coat from Jim Carter. It's good for 5' away, and I haven't done any polishing yet. I've painted close to 50F, which is the lowest that the instructions say and it's worked out well.
I say go for it. I'll second what Mark said.
Maybe on second thought, Maaco, here I come.

NOOOOOOO!!!!!
Years ago, a friend had a pickup painted by Earl Scheib (a forerunner of Maaco.) It wasn't even a 100 footer, as they even got paint on the tires, failing to mask them off. I don't recall how it lasted, but I suspect it started falling off the truck after a year or so.
