Bar’s Leaks Block Seal Head Gasket Sealant Head Gasket Repair 20 oz Mfr# 1100 – Ace Hardware

Description For most vehicles, this is the last chance before going to a junk yard or paying an expensive repair bill. This product 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 permanent ceramic type seal. Your vehicle is a good candidate for this product if it can idle for 20 minutes without overheating or having to add coolant. Works effectively on cast iron or aluminum blocks & heads. Detailed instructions on back booklet label take you through each step of using the product. *Find the HEAD GASKET REPAIR 20OZ at Ace.
