Best way to paint A bodies???

I'm in the process of painting my Valiant. I haven't made any final decisions on how to paint it as I'm just starting the priming. My research says it depends on whether you are using a metallic or not. With a metallic it would be better to paint it assembled. This doesn't mean that you still couldn't paint some parts while they were off of the car but that the outer surfaces of the doors, hood, trunk and fenders would be painted while on the car. With a solid color it doesn't matter so much. I'll definitely paint the engine bay and trunk first as well as the underside of the hood and trunk lid. I'm still not sure on whether to paint the door jambs or not. If you paint them you will have lines. As far as disassembly goes, it depends on what quality of a job you want and how much time and money you want to spend. Every car I do ends up being a bigger and bigger job due to the extent of disassembly. It sure looks nice though. :-D
