Not trying to threadjack, my thread has been long lost and we are pretty much on the same track. Here are some semi-final shots of the satin job I've been working on. I ended up having a guy at work paint the lower clading and bumpers gloss with a base/clear. Turned out pretty darn good for being done in a mixer shop! The hood still needs to be fixed and painted, and I will end up paiting from the trim lines up, on the bumper satin to match the ca's lines.
If you go with the single stage, I would stear clear(no pun intended) of the hot rod flatz. This is the second time I sprayed it. I am definetly no pro, but without a booth and the inability to buff a flat paintjob, it is hard to get this paint to come out great. It was cold when i sprayed it which had some effect, but overall the laydown was really inconsistant.
