Water being the greatest friend and foe to the marine industry, this remarkable, specially formulated grease has the ability to repel water, displace rust and corrosion, and actually forms a chemical bond with metal. The bond is extraordinarily strong and the platelets which form during the chemical reaction are so super slippery that, as in the other marine products, friction is reduced up to 80% and the ability to repel water reduces wear dramatically. Boron CLS Bond is biodegradable. 14 oz (414 ml) US Patent # 5,431,830
