Marine Tuf-Cloth was developed for U.S. Navy SEALS, based upon the successful lint-free, long-lasting, oil-free Tuf-Cloth, the replacement for oil and silicone rags for knives, tools, and firearms. Sentry SolutionŐs proprietary formula of non-toxic, dry-film corrosion inhibitors and lubricants provides a fast-drying, water-displacing, micro-bonding crystal barrier against rust, friction and wear. The Marine Tuf-Cloth is formulated with additional anti-corrosive ingredients. These special ingredients enhance protection of firearms, fishing tackle, dive knives and gear, boat and trailer accessories against the highly corrosive effects of saltwater and high humidity. Marine Tuf-Cloth also offers superb protection for gear that is stowed away long-term, keeping it rust-free and out-of-storage ready for your next adventure.
