FWIW, I used paint I got from Jim Carter (PPG ALK-200 - an acrylic enamel) and shot everything except the bed (which I painted outside) in a tent I set up in front of my garage. As long as the outside temp was going to be above 50F, I painted parts. I got varying degrees of success, mostly because I was learning as I went. Some of the first parts (cab, fenders, etc.) had some orange peel (appropriate because of the color

), while other parts (hood, running board aprons, and the passenger door) came out nice and smooth with very few defects. The paint is easy to color sand and buff out to remove the few dust nibs and minor orange peel. The gun I used was a pretty inexpensive PPG Accuspray gun with disposable tips and cups. For the amateur painter, the cleanup is very easy. You also need a good compressor with water removal filters ( I used a final filter right at the gun.)
The PPG Acrylic Urethane (I think it's AUE-300) that 78buckshot mentioned would also be a good option.
I think it's worth a try for you.
