My piece isn't pitted very bad but I'm not going to leave it like that. I had an idea that wouldn't cost much...if it would work.

When I had my fasteners zinc plated, a few of the really small screws didn't take the plating for some reason. They ended up putting them in the "nickle" tank. Would this work on the horn ring?

If I sanded out the pitts and smoothed it out the best I could, would the "nickle" stick to the pot metal? Would it even survive the acid bath and plating process?
