I've been doing my first single stage job on my car as well. It is plum crazy purple. I would say be very aware of how tight you are overlapping your passes, I'd say 70 to 75% overlap has worked very well for me. I also turn the mixture down a bit for a smaller droplet and a little less material, with the extra effort of overlapping my passes better the paint tends to accumulate just right with the toned down mixture setting. I have been surprised how well it has layed down with this strategy. I also move quite a bit faster than if I was spraying clear coat. I think where your color is not a high metallics color it will be quite straightforward for you getting good results, and of course the cutt and buff will work great on the non metallic single stage. I wanted to paint my car green go, or sublime but eventually decided to go original with it.
