Review: Best repair or reinforcement product for metal or plastic available - My buddies give me a hard time over how often Im trying to build or repair something in my shop with J.B. Weld. It's the best product out there when you need to reinforce or repair any thing made out of metal or plastic. If you look at my desertcart purchase history you would see why my buddies give me a hard time. I go through one double pack of this stuff a month. There's no other product like it out there
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.

Very strong bond for iron gate repair. Easy mixing. Seems to be holding up impressively so far. Definitely would recommend for any small metal bonding job.
