A Slick Product

Rem OilRem Oil is not really a penetrating oil like good old WD-40, but it is probably a better all-purpose spray can lubricant. It was designed as a gun cleaner/lubricant, and it cleans dirt and grime from exposed metal surfaces while displacing moisture from the pores in the surface of the metal. It also contains Teflon which provides a thin, long-lasting film that keeps things working smoothly by reducing metal-to-metal wear.
