Blue Magic 8024 ThermoSteel High-Temp Metal Repair
ThermoSteel, from Blue Magic is the highest temperature sealant on the market. This sealant is designed to withstand temperatures up to 2400oF, far beyond what some other high temperature sealants can withstand. This makes ThermoSteel ideal for repairing difficult repairs, such as those to barbecue grilles, exhaust manifolds and furnaces. The compound withstands contact with direct flame, which not all high temperature sealants can do. It is a thick compound, which allows it to fill cracks, holes and pits. ThermoSteel comes in three ounce packages for home use, as well as a 25 ounce professional size.
