All right stop the snickering. But it does depend on its purpose. I think one of the better products is Nickolas 2105 spray that you get from McMaster Carr http://www.mcmaster.com/
P/N 76885T732105. A lot of jewelers use. For product info check out this website but you can not buy the aerosol cans from them.

Renaissance Wax is a brand of wax polish that is widely encountered in antique restoration and museum curation. Although not appropriate for all materials, it is known to and used by almost every collection. It is also used as a primary finish for cabinetry and furniture.
To quote a typical commercial supplier of conservation materials, it is used, to revive and protect valuable furniture, leather, paintings, metals, marble, onyx, ivory etc. Freshens colours and imparts a soft sheen.[1]
Wax coatings for conservation are most widely, and least controversially, applied to metals. This has several objectives: to produce a barrier that excludes moisture and oxygen from the metal surface, to ensure against further introduction of contaminating elements by handling, and to provide a protective layer over anti-corrosion undercoatings.
Waxes should not be applied to materials with deliberately loose or powdery surfaces.
it should work.
