Web Team Brownells Rust Veto is a soft, medium dark industrial-grade grease with a powerful combination of highly refined petroleum oils and waxes, plus corrosion and oxidation inhibitors, that preserves and protects stored firearms from rust and corrosion for years. The application and effectiveness of Rust Veto are the same as Cosmoline. It liquefies when heated to 140°-170° F., so you can immerse parts for complete penetration and coverage of intricate shapes and recesses. Melted Rust Veto can also be brushed or swabbed into/onto the metal to be protected.
