## Description

J-B Weld is The Original Cold-Weld two-part epoxy system that provides strong, lasting repairs to metal and multiple surfaces. Mixed at a ratio of 1:1, it forms a permanent bond and can be shaped, tapped, filed, sanded and drilled after curing. At room temperature, J-B Weld sets in 4-6 hours to a dark grey color. Full cure is reached in 15 hours. J-B Weld has a tensile strength of 5020 PSI and sets to a hard bond overnight. It can withstand temperatures up to 550°F when fully cured

Review: Works great on many things. Have used for many years. - Always been a fan of J-B Weld. Others seem just as good most of the time, but have stuck with what I know. I like the syringe applicator and much less messy than the squeeze tubes. If mixed good and surface prepared and cleaned this always seems to hold and work long term. Easy to use and durable. For the money it isn't the cheapest, but you always know what you are getting.
