    Locking gas cap

    I purchased a locking gas cap from a Chevy dealer shortly after purchasing my '69 in 1971. The chrome has pitted and I would love to have it replated. The plated part is easily removable from the locking mechanism. Can this be replated? What is it made of- it's not magnetic and I suspect it is pot metal but it feels heavier and more solid than pot metal. If it is pot metal. can the chrome be removed in the same way it is removed from steel- reverse plating in diluted sulfuric acid? Thanks for any advise.

    It's zinc diecast ("pot metal"). Yes, it can be re-plated by platers accomplished in working with zinc diecast but these are generally "few and far between". Plus, you have the added need of restoration of the zinc diecast due to the pitting. That's another specialized skill. By the time all is said-and-done I expect it's going to cost you more than just finding a good used or NOS cap.
