Ceramic Motor Seal from Irontite is designed to permanently seal leaking head gaskets, cracked heads and blocks in aluminum or cast iron. It coats the engine and prevents formation of rust and water corrosion, and it seals porous castings in the cooling system. Users add it to the radiator after removing antifreeze, and it stops coolant leaks and promotes heat dissipation for added engine power. Ceramic Seal is not compatible with antifreeze. All antifreeze must be removed before treating.
