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.

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.

Excellent product
JB weld is the best stuff on the planet.

Cures as hard as steel!
Impressive how solid this stuff is when it’s setup over night. It has the same consistency as steel! Grinds off smoothly and makes a hard bond. Works as intended, recommend this product.

Easy to use
I used this to fix a kitchen sink faucet handle, the gear stripped and would free spin. The instructions were clear, I used the cardboard Amazon box to mix the 2 parts, applied it to the gear sticking out of the sink, stuck the handle back on it, and left it overnight. By morning the sink handle worked like new! It's been about a week since applying it and its still holding strong. The shaft sticking out of the sink was metal, and the gear inside the handle was plastic and striped smooth. I was worried it wasn't going to bond well but a week later and its still going. Great product IMO.

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.

Bought this epoxy adhesive to glue magnets onto my front door letterbox which was rattling during recent high winds. The magnets, now securely in place, allow a firm grip of the outer flap without the postman noticing the additional effort required in lifting the flap for mail. The epoxy resin fixes metal to metal and is completely cured within 12-18 hours. I had to take care that only the magnets were glued to the metal parts of the letterbox as any overspill would have resulted in the letterbox being totally sealed as this resin sets rock solid.
