Excellent for all weather applications
Likely the best epoxy you can buy legally. Stuff cures to a strength we have been able to break yet. I have used it on shower doors, boats, cars and anything I can think of where the weather is going to be a factor. It works well.

i use this stuff in crafting and i gotta say it works great. super easy to use, just mix parts A & B. it dries to a very dark glossy grey. its smooth and is very durable. i find that it holds the joint very well. these are small tubes but go a long way, plus the price is right so its all a win win

Great for Repairing a Fountain
I have a multi-tier, resin garden fountain that is around 10 years old. They don't make that fountain anymore & similar ones are 4 times the price now. I can't bear the thought of having it dumped in a landfill either. So every spring I check the fountain for hairline cracks & tiny holes using a flashlight. This JB Marine Weld makes it easy to repair those spots. I let it dry overnight, touch everything up with a little spray paint and the fountain is functional again. For larger holes, pliable screen netting can be cut to shape and then covered over with this welding paste. It dries solid and is alot stronger than you think. Highly recommend this!! Lots of possible uses with a little creative thinking.

Reliable, very durable weld, used to reinforce ceramic crockpot
I like this weld. I used it to shore up a developing crack on a crockpot. Extends the life of the crockpot, which would be hard to replace. The cured material is just as hard as the ceramic. The patch I put in place did partially break off after many years, however most of it is still in place.

tarda horas en endurecer para fijar las piezas, pero cuando seca queda sólido de verdad
si eres fan de los epóxicos que en minutos endurecen al grado de fijar las dos piezas a unir, no es el caso con este epóxico. Tarda literalmente de 4 a 6 horas para endurecer un poco como para fijar las piezas , debes de sostener las piezas a unir con una prensa o algo así porque de otro modo no se sostienen. Y para el secado total tarda de 15 a 24 horas. Es un epóxico LENTO, muy lento, no de los que fijan en minutos. La masilla la puedes seguir trabajando hasta dos horas después de prepararla lo cual es una ventaja dependiendo de la situación. Una vez que seca completamente después de 24 hrs, queda definitivamente adherido y sólido. Por eso cambié mi calificación

OTTIMO!!
Ottimo prodotto! Usato per la saldatura di parti in carbonio. Una volta mescolato si ottiene una pasta abbastanza densa e appiccicosa. Si mantiene morbida ed applicabile per almeno un'ora e mezza a circa 18/20 gradi, temperatura minima per la catalisi, con il passare del tempo inizia l'indurimento. Per favorire la catalisi fino a completamento della polimerizzazione, soprattutto in Inverno, consiglio l'esposizione delle parti unite vicino ad una fonte di calore continuo, tipo una stufetta, in modo da avere il completo indurimento della colla applicata in tempi molto ridotti: 90 minuti per un buono indurimento. Poi attendere le 18/24 ore per ottenere le prestazioni riguardanti la tenuta in trazione e la completa lavorabilità. Spedizione eccellente.
