The gun oil that's a rust proofer too! Proven in over 40 years of all-climate performance to prevent rust in the worst possible hunting and shooting weather and locations. Definitely not a space age chemical that raises hob with gun finishes and bluing, but a blend of petroleum distillates specially formulated for use on guns, tools and machinery. Penetrates pores to get down under fingerprints and moisture, then leaves an invisible film to protect and lubricate. Unlike general purpose water displacing rust proofers, RP2 won't gum-up in the nooks and crannies. Pints are supplied in a handy, pump spray bottle.
