Star brite Marine Formula White Lubricant is a waterproof anti-condensation, anti-wear, anti-stick lubricant that does not wash away, break down, evaporate, spread, or get dirty. It prevents corrosion between different metals by preventing seawater from ever reaching the surface. No more seizing, sticking, or galling of stainless steel and other metal alloys. Use on screws, bolts, plates, couplings, electrical connections, contacts; anywhere seawater can corrode or seize metals. Provides years of virtually friction-free protection for winches, anchor winches, turnbuckles, blocks, steering systems, shafts, pumps, zippers, toilets, screws, snaps, fishing reels, and even firearms.
