STEEL SEAL: PERMANENT REPAIR

Steel Seal is a unique mixture of chemical compounds that have been specially blended to react under sufficient heat and pressure to create a hardened seal in the damaged area of a head gasket or block.

However there are lots of products claiming the same thing.

While there are other products that claim to repair a blown head gasket in a similar way to Steel Seal and these products are predominately comprised of little more than Sodium Silicate and dye.
