Just came up with another idea.......Do you know anybody in the bodyshop business, or know who's going to do your final paint? I'm guessing you're painting this at your place. Why not offer them $250.00 (or whatever) to stop by your place on a saturday morning with THEIR gun and have them do it quick. If you have it 100% preped and all they have to do is squirt the paint it won't take that awful long.
