🔥 Fix it once, fix it forever with Extremeheat Metallic Paste!
J-B Weld Extremeheat is a 3 oz high-temperature resistant metallic paste designed for permanent repairs on iron, steel, and metal surfaces exposed to heat up to 1000°F (537°C). Non-flammable and free of solvents and VOCs, it forms a bond stronger than steel without the need for torch welding. Once cured, it can be drilled, machined, or sanded, making it ideal for repairing exhaust manifolds, grills, furnaces, and other high-heat metal components.
