I used the search function, but couldn't find info I wanted, so.... My question is: how does one go about polishing die-cast metal parts to a mirror-like sheen? The piece of metal I'm dealing with is rather small-- less than 2 inches, in a tubular shape. I would like to ultimately coat it with a clear yellow coat, to obtain a shiny gold finish. So what tools/compounds should I use? I should mention, the piece is already fairly shiny, but there are surface imperfections (like cast lines, some orange peel pattern in places) that I would like to get rid of as well.
A detailed response would be greatly appreciated.
Also, is using isopropanol to strip off paint from die-cast metal a good idea? Does it hurt the metal itself somehow?
