Brownells Rust Veto, 1Lb

Long-term firearm storage demands serious rust protection, and Brownells Rust Veto is a purposefully formulated grease engineered to do exactly that. Built as a direct successor to the now-discontinued Cosmoline formula, Rust Veto combines refined petroleum oils and waxes with dedicated corrosion and oxidation inhibitors to shield stored guns from rust and corrosion for years. Whether you're protecting a safe queen during an off-season, storing heirloom rifles, or preserving firearms through seasonal breaks, this 1-pound container delivers industrial-grade defense against the moisture and oxygen that cause rust.

The application method is where Rust Veto earns its keep. Heat it to 140°–170° F and the grease liquefies, allowing you to fully immerse components for complete coverage of every nook, crevasse, and hard-to-reach detail. Alternatively, you can brush or swab it directly onto the metal surfaces you want to protect. That flexibility matters when you're dealing with takedown rifles, pistol parts, or intricate trigger groups where complete saturation is the goal.

If you grew up using Cosmoline, Rust Veto will feel familiar—the application, effectiveness, and peace of mind are all there. A single 1-pound tin covers significant ground, making it practical for protecting multiple firearms or building a reliable deep-storage routine. Keep one in your safe, your workbench, or your cleaning kit and ensure your best guns stay rust-free for decades.
