ULTRA Tef-Gel Lubricates and eliminates corrosion between dissimilar or different metals by preventing saltwater electrolytes from getting to the surface of those connecting metals. Prevents seizing, galling, rust, and friction welding of stainless steel, inconel, and other nickel alloys. For use on bolts, screws, plates, hitches, electrical connectors and contacts, and anywhere saltwater can affect joining metals. Works great on fishing reels. Easily applied with a mascara brush provided. ULTRA Tef-Gel contains no volatile solvents, will not evaporate, dry out, or wash away in salt water, providing long lasting protection and ease of disassembly years later.
