"Super Lube Anti-Corrosion Gel has superior synthetic dielectric compound specifically formulated to provide better protection than typical grease. It has excellent resistance to saltwater and most detergents. Contains PTFE, provides improved anti-wear properties, is waterproof, not washed away by acids or alkalis, and resists temperatures to 750 degrees F. The SYNCOLON-TM (PTFE) particles in Super Lube's unique patented formula are held in constant suspension ensuring they will always be evenly applied to the lubricated surface as needed. "
