JB Weld 8267-S SteelStik Epoxy Putty Stick
JB Weld SteelStick is a steel reinforced epoxy putty. That means it has steel flakes in it, as a filler. The steel flakes work like fiber reinforcement would, making the cured JB Weld a very hard mass. Once cured, JB Weld can be drilled filed and tapped, making it ideal for automotive or machinery repairs. It handles high temperatures well, up to 300 degrees, making it ideal for vehicle exhaust systems. The putty sets in five minutes and fully cures in 1 hour, resulting in a final strength of 900 PSI. Although it is steel reinforced, it won't rust.
