Great product.
The product worked much better than I thought! Stronger than it was originally. Extremely happy would recommend this to anyone & I'd buy it again.

You won't regret buying this. A-One!!!
This is my go to product for everything fix-it. Love this stuff. I have fixed everything from exercise equipment to kitchen utensils. The weld on my exercise bike has lasted 8 years and still seems good. If you don't want to replace it, JB Weld it. I swear by it.

One of the greatest adhesives in the world
JB Weld is the best epoxy I have ever used. I use it all the time for repairs, some that are downright strange. Example: I don't function very well in the AM before coffee, so I accidentally bumped the glass coffee pot for my coffee maker. Make a small crack on the outside of the glass, just above the bottom. So I thought, lets test this: so I applied a small square of JB Weld over the small crack (on the outside of the decanter) about the size of a postage stamp. Let it cure overnight. That was a week ago, and it's doing just fine. I can't believe it...it adhered to the glass and is holding like a crazy man. Saved myself $30+ on a new decanter. I repaired one of my wife's favorite earrings when the small ring that held the dangle broke on one side. Tiny amount of JB on it, let it sit overnight, and gave to her next day. She re-fell in love with me. :) One of the properties it has that I really like is how smooth and easy it is to mix and apply. Many epoxies have thick consistency and are difficult to mix and apply smoothly. JB goes on like warm butter, but dries hard as metal. I'm always using it for something and it's never failed me yet.

Love JB Weld
You pay a small premium for JB Weld but worth it. Their products, including this one, are worth the extra price. Follow directions and let dry for even longer and it creates a permanent bond.

Its ok
even with good surface prep, aggressive mixing, and liberal application, i still get a better result with other products. But for larger glue-ups, this is better than superglue, albeit weaker.

Epoxy Works well, 24 hours for full strength, tubes had a lot of air.
J-B Weld 8281 arrived intact. There was no tube leakage and when used appeared fresh. The white and black combo gives a grey final product. I was not sure it would bond with my application. I needed to repair a cheap broken valve at the bottom of a 60 gallon rain barrel. The barrel is a slippery brown plastic. I tried heating the plastic and screwing a threaded galvanized pipe nipple into the plastic but it still leaked. The Epoxy is messy to mix, I used a small flat piece of wood to stir components. Takes 24 hours to thoroughly harden but seems very strong and it stuck well to the plastic barrel and galvanized pipe. It is difficult to get a neat bond but I didn't care about that appearance. The rain barrel is now functional with no leaks, very happy. The Epoxy is a bit expensive and when I opened there was a considerable amount of air (perhaps 1/3 of volume) in each tube so there is less product than you think making it more expensive. I also used it on a small concrete frog statue which had the head broken off. It worked well to make that repair as well. These fixes are only several weeks old so I cannot comment on longevity.
