Sentry Tuf Glide 1/2oz, A dry film rust inhibitor and lubricant, replacing oils and silicones. Designed to be used with TUF-CLOTH and MARINE TUF-CLOTH it makes difficult to access areas of firearms and equipment easier to protect. TUF-GLIDE should be used on all types of metal finishes, and woods for protection and lubrication. It makes oil and silicone products obsolete. Sentry uses state-of-the-art dry film technology to make TUF-GLIDE a superior, long-lasting product for both rust protection and lubrication. Sentry developed a proprietary formula of dry film rust inhibitors and lubricants which have a natural affinity for metals. Pure mineral spirits is the carrier, so TUF-GLIDE is fast drying and easy to apply. TUF-GLIDE penetrates hard to access areas and displaces water. It provides cleaning, rust protection and lubrication. Pure mineral spirits carries the active ingredients and provides cleaning action. It evaporates, and Sentry's proprietary ingredients bond to the surface; this bonding ensures long-lasting effectiveness. TUF-GLIDES' waterproof protection will not wash off and won't thicken in the cold (even down to -40°F/-40°C). It will not attract dirt like oil-based products, nor is it a slippery film like silicone. It is great to use on wood and is safe for most plastics.
