The original cold weld that never quits
Fixing anything is basically doable with JB weld. This is your new best friend, or old friend in my case. I used it a lot in the past, and I always come back to it for any work around the house. Super glue is fine and all that, but this is the real deal. It’s called weld for a reason: it’s tough, reliable, and practically indestructible once it fully cures. Pros: 1- Massive value for big jobs: this is perfect for large-scale projects where those tiny standard tubes just won't cut it. You get enough volume to handle multiple repairs without worrying about running out mid-mix. 2- Industrial strength: once fully cured, it boasts a tensile strength of 5,020 PSI. It’s essentially "liquid steel" that you can drill, tap, file, and sand just like the metal it’s repairing. 3- High temperature tolerance: it can withstand constant temperatures up 287°C, making it ideal for automotive or plumbing repairs that see significant heat. 4- Universal versatility: while it’s famous for metal-to-metal bonding, it works incredibly well on wood, plastic, tile, PVC, and fiberglass. Overall, this is the gold standard for heavy-duty epoxy. It’s industrial-strength, easy to mix, and consistently delivers a permanent bond. If you want a repair that’s "fixed for good," this is the stuff you want in your toolbox.

j-b weld
great product had a broken concrete bowl from an old bird bath applied j-b weld as per instructions and in 24 hours the birds were splashing around, also used to fix a garden cultivator that was loose in the handle, used outdoors so no odor noted was easy to mix, recommend and would buy again

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.

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.

Excelente producto!
Yo empecé a revisar acerca de pegamentos y encotré este que parecía demasiado bueno para ser verdad... Una, verdadera joya! tiene un gris rata horrible y huele aún peor (antes de secarse, después es completamente inodoro), pero si se usa siguiendo las instrucciones y con la proporciones 50/50 es sólido como el acero. Lo he utilizado desde para pegar partes móviles de jugetes, hasta para sellar una tubería picada de cobre y reparar una de PVC, esto tiene cerca de seis meses y no hay ningún rastro de que se afloje o se diluya. Tengan en cuenta que es un pegamento epóxico, no instantaneo; una vez aplicado, toma como 4-6 H. que se empiece a solidificar (aqui todavia se puede ajustar o mover la pieza) a las 24 H. esta completamente solidificado y a las 36 está completamente curado.
