Steel Seal

Steel Seal can permanently seal blown head gaskets, warped heads and cracked engine blocks. Simply pour Steel Seal into the radiator of a cold engine.  When the engine is started and reaches its operating temperature the mixture is drawn into the damaged areas by the heat and pressure caused by the head gasket fault, which then seals the cracks with a thermo-chemical bonding process. Once the bonding process is complete and the engine has been allowed to cool the chemicals become inert, so there is no reaction when other products are added to the cooling system. Steel Seal also offers a lifetime money back guarantee
