I have wondered about the same things--got an experiment machine myself that needs a finish redo. Blast (and keep it out of the insides?), chemical stripper, what about cleaning it off to prep for primer and paint? I have read about Billy's repaints, and I believe he uses high-end automotive paint, taking it down to bare metal first, then using very nice clear over it and any decals, flames, so on. My brother-in-law has agreed to help me out if I do decide to try it one of these days, so I'm really interested in anyone else's experience!
