Re: Paint Removal
Lauer claims that cured Duracoat can only be removed by abrasive blasting. That said, some have reported good results by using various paint strippers.
For plain old spray paint, I'd start with mineral spirits and a rag. FWIW, I once sprayed brake cleaner on a gun that I didn't realize had been spray painted. Most of the paint came right off, so that's an option for metal; kinda hard on plastics, though.
