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.

Easy to use and reuse multiple times.
Great product. Easy to use and reuse multiple times. When it hardens, it really is tough. Perfect amount of time to use and adjust before it cures. Well worth the price.

Great for emergencies
I like keeping some of these in my tool box for unique emergencies. Easy to use in a pinch. Durable and gets the job done!

Used properly, JB weld products are on par with industrial grade epoxy adhesives.
Let me preface: I work as a QA/QM/QC engineer with hard state electronics, I am self-taught in how to do electrical work (house wiring) and also self taught in the use of machine shop equipment (drill presses, lathes, so on and so on). Part of my work is also with "potting" compounds, that is, encapsulating the industrial electronic piece in various lacquers, fiber glass resins, high thermal condustivity and high dielectric strength epoxies. Suffice to say, I know what I am talking about. AB is on par with these industrial grade "potting" compounds. There is a faucet in my house that has that stupid design where the handle is on a stem that is held in place with a set screw (a screw with no head). After repeated usage it came undone. The valve still works but the handle did not stay in place. So I used this AB product to back fill the orifice in to which the valve stem was inserted and then cranked a flat head screw in to the port for which the set screw was intended. It's been in service since then with ZERO FAILURE for several years, and the hand is solidly held in place, there is no slop in the handle's movement. It's "welded" in place by the back fill with the JB weld and the screw which held it in place until the JB weld putty set. There is another faucet which was a much more complicated fix, so I won't describe that one. All one needs to know is with JB weld and ingenuity I made the handle effectively shatter proof, you can slap the handle down with a thunk and it will not come undone.

Super Strong
I used this to reset my wifes bumper cover back into place after a misfortunate accident while teaching my daughter to drive which broke the connecter clasps. after the cure time was up and the painters tape was removed, the bumper cover has been securely in place for the last 20,000 miles over all sorts of terrain! Worth every cent!

J-B Weld works great.
Wish the package would have a perforated back flap, so you can store the unused portion in its own container without getting goop everywhere.

Love that JB Weld
I've used JB Weld on so many projects and I am always happy with the results. It's super easy to mix with this syringe dispenser and it cures quickly. It sticks really well and holds as well or better than the original material. I used this to patch a hole in a lawn mower deck, repair many plastic parts that you would normally throw away, and even used it to cement a chipped piece of concrete back into my driveway. It makes permanent repairs that last as long as the item being fixed. Great value to save a broken item.

This product is very good. It cures very well and it sets properly hard. Good for industrial use. I used it in my car. For a coolant tank crack but unfortunately didn't work well for me, but the product is good.

This epoxy is perfect. I use it to weld pinbacks to enamel pins. It's so sturdy. Even with the expensive shipping to the Netherlands worth every penny.

JB Weld are trying to charge import duty on top of the listed price. It doesn't say anything on the product details that this is due on top of the purchase price. Someone there is getting mixed up about this one.
