We've all been there… Stainless steel screws in aluminum parts become electronically welded together after a few months on a boat. When this happens, even small, simple repairs can turn into nuckle-busting nightmares. Tef-Gel PTFE anti-seize paste ensures that doesn't happen to you. Tef-Gel prevents seizing and corrosion on fasteners in the marine environment. It fills all the cracks and crevices between threads so water can not seep in and cause corrosion and electrolysis. Also use as a bedding paste between dissimilar metals. Tef-Gel applied between electrical contacts and connectors does not increase the resistance of the connections even at hundreds of amps, maintaining the integrity of EMI shielding. Use it, generously.
