Cosmoline: Was first developed as a petroleum based product for military storage applications requiring a rust inhibitor.  It has a thick, oily wax-type viscosity.  It can be removed by scraping, or applying gentle heat, and washed off completely with common light solvents.  A song was sung by GIs that "cosmoline" will keep my weapon clean . .  ! . . .
