Head Gasket Repair is scientifically formulated to permanently seal coolant leaks that are the cause of most overheating problems. For most vehicles, this is the last chance before going to a junk yard or paying an expensive repair bill. This patent pending repair contains a blend of Aramid and refractory fibers giving the strength of a bullet-proof vest and the heat resistance of fire-proof clothing. As these particles penetrate a crack or the blown head gasket area, they lock together and bond forming a hard ceramic type seal.

• Uses a special liquid glass formula that is designed to seal cracks and leaks where others fail.
• Antifreeze MUST be flushed from the cooling system before using.
• Works effectively on cast iron or aluminum blocks & heads.
• Detailed English / Spanish instructions on back label take you through each step of using the product.
