Brownells Rust Preventive #2, Quart, 32Oz

Brownells Rust Preventive #2 in the convenient quart size is the workhorse gun oil trusted by shooters and hunters for over four decades. This isn't a trendy synthetic or aerospace formula—it's a proven blend of petroleum distillates engineered specifically for firearms, tools, and machinery. Whether you're storing rifles in a humid climate, maintaining handguns after a day in wet conditions, or protecting blued and finished surfaces from corrosion, RP2 delivers reliable rust protection without the downsides of generic lubricants.

What sets Brownells RP2 apart is its ability to penetrate deep into metal pores, working underneath fingerprints and surface moisture to establish a thin, invisible protective layer. Unlike broad-spectrum water-displacing oils that can accumulate and gunk up in tight spaces and crevices, RP2 stays clean and won't build up residue where you don't want it. The formulation respects gun finishes and bluing—it protects rather than damages the surfaces you've invested in.

The 32-ounce quart format gives you enough product for regular maintenance across multiple firearms and gear without constant replenishment. Whether you're prepping for hunting season, maintaining your range kit, or running a small armory, this size strikes a practical balance between coverage and storage. Keep it on hand for touch-ups, storage prep, and routine care whenever weather or environment poses a rust threat.
