Do you have a spare/junk/cheap pair to test on? I would imagine rouge would work fine as it’s commonplace on stainless bands of watches and works well, or even something like mag wheel polish (assuming that’s what you mean by chrome polish). Something like Blue Magic or other polishing agent to buff metal to a brilliant shine. Keep in mind though if the metal is bare, would work fine but if it has clear coat on it, stick to polishing compounds that would bring out the shine on it. I would test on cheap metal frames first. If you do happen to try, please post some pics.
