I use Renaissance wax mixed with a bit of lamp black to highlight and protect French grayed metal engravings. Also waxed some engraved aluminum guitar inlays about 6 years ago and so far no sign of oxidation...still nice and shiny.

I'm with Stan on the Johnson's paste wax for protecting a gun when out in the weather...no rust after several years in the Kodiak, AK salt environment.
