Re: Powder Coating Eyeglass frames
If the metal surface still conducts a charge, the powder will apply quite easily. Even if it doesn't, then heating the surface will do the trick. Adhesion (after curing) shouldn't be much of a problem for most powders. Most people aren't too rough with their glasses anyway, but you could do some testing on an old pair.
Sometimes a previous coating can bubble up through your powder during the cure cycle, but it looks like you'd get the thumbs up to try it out!
