Brownells Rust Preventive #2, Gallon, 128Oz

Brownells Rust Preventive #2 is a dependable gun oil and rust preventive formulated specifically for firearms, tools, and machinery. If you hunt or shoot in wet climates, humid seasons, or challenging field conditions, you need a protective coating that actually works—and this gallon size gives you enough to stock your cleaning bench, your truck, and your off-season storage routine. Unlike generic penetrating oils, RP2 is built on a petroleum distillate blend engineered to handle the worst weather while respecting your gun's finish and bluing.

The formula works by penetrating deep into pores and surfaces to displace moisture that hides under fingerprints and corrosion. Once it does its job, it leaves behind an invisible protective film that lubricates and shields metal from rust. That means real protection in the field and during storage—whether you're hunting in the Pacific Northwest rain, leaving a rifle in a truck bed, or storing gear through a humid off-season. The 128-ounce gallon size makes it practical for serious shooters and hunters who maintain multiple firearms or share supplies with a shooting group.

What sets RP2 apart is what it doesn't do: it won't gum up or attract dirt in tight mechanisms and hard-to-clean areas. Four decades of proven performance across varied climates backs the formula. This is straightforward, gun-focused chemistry—no exotic compounds that strip finishes or create headaches.
