FiberFix Heat Repair Wrap will withstand temperatures up to 850°F! Make high temperature repairs that you didn't even know were possible! The industrial-strength fibers combined with a specialized resin will harden like steel so you get a permanent fix that is perfect for high-temperature applications. Just activate it with water and wrap it tightly around the broken object and it’s completely repaired within 10 to 15 minutes. Use it to repair household and outdoor objects from high-temperature hot water pipes and furnaces to mufflers, other auto parts and utility units. The wrap is heat and cold resistant and air and water tight. You can also sand and paint it so that no one will know the difference. There is one 2"x70" wrap in package.
