Zinc Dichromate (Gold Iridite).
This gold plating has red and green running through it. It is the same finish found when opening most original boosters. Metal that has pitting will still have pits under the plating when replated unless polished out. This plating is far superior to any spray can products available
your boosters, caliper brackets, alternator fan, master cylinder covers,
etc. to their original finish.
