Brilliant stuff!
Bought this to seal the holes in a bowl planter for a mini pond. It's fabulous stuff and works really well. I highly recommend it.

Amazing stuff
This really does the job. Used when our old porcelain toilet cistern developed a crack and started weeping from it. As an emergency measure I drained it dry, plastered some of this MarineWeld inside along the crack and a good margin either side, left it dry for the recommended 15 hours and refilled. That was a full 5 years ago with not a trace of water escaping. Then a fine crack appeared in another part of the cistern, and I did the same thing again and used up the other half of the original tubes which had sat in the garage and were still perfectly usable. Again, perfect result, no more weeping cistern. If I replace the cistern I'll have to completely replace all the fittings in that room as they're all matching and well over 30 years old and still otherwise performing absolutely fine. Massive save, thanks JBWeld, brilliant product! I bought it again because I always want some handy in case of future need :o) Originally recommended by a friend who clearly knows his materials!

Great product
used to stick magnets back into a magneto on a motorcycle, charging system works now and combined with the putty the magnets will never move

Not for me
Wasn't what I was expecting, more of a paste than a epoxy , like chewing gum, hard to work with.

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.

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

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
