JB Weld 8277 Waterweld (Pack of 3)

In late July 2017, a $6 stick of JB Water Weld saved my ancient but new-to-me 40-foot boat from sinking after a 5/8" through-hull bolt sheared off. The unexpected appearance of a highly undesirable new water feature shooting up about three feet from a hole in the hull under the aft cabin of my floating home was somewhat disconcerting, but I immediately thought of the 3 & 1/2 JB Water Weld sticks that I had added to the emergency supplies in the equipment locker on the day I bought the boat. Perhaps the brittle old battery-powered bilge pump would have kept me afloat long enough to get the boat hauled onto dry land, but batteries, and the diesel fuel needed to recharge them, can only last so long. Whereas epoxy is forever. Or darn close, in most cases. In this case, the Water Weld worked flawlessly, and the repair remained bone dry and rock solid for over six weeks, until I was able to have the boat hauled out for refitting and repairs. (Including the addition of a back-up bilge pump, lol.) I've already restocked the emergency supplies with 3 more sticks of JB Water Weld. I've also used Water Weld at home for many years, to repair a table saw guide lock-down handle, a leaking lawnmower fuel tank, plumbing repairs, car repairs, broken kitchenware, untold minor knick-knacks, and plugging a leak at the bottom of my swimming pool. The table saw repair worked so well that I could use the guide, which locked down in place with a lot of shearing stress on the epoxied over-center lever/handle, to make cuts accurate to 1/32 of an inch for more than a decade, until I gave the saw away. Probably still works great, and I've kicked myself a thousand times for giving it away, because the new ones are so cheaply made. Seems like you're usually better off epoxying something old than buying something new these days. The pool repair was still holding back 10,000 gallons of water when I sold the house 12 years later. Like any adhesive, it's really important to read and follow the directions, and the better you prep the surface, the better the epoxy is likely to work. The first time I fixed the table saw with Water Weld, I did a slapdash job, and the repair failed after a couple years. My fault, not the epoxy's. But I did it right the second time, properly prepping the surfaces, and it lasted more than a decade. My very wise mom introduced me to the original JB Weld epoxy 40 years ago, and I'm a long-time satisfied user of a wide range of their products, including JB Weld Original, Steel Weld, Wood Weld, and of course, Water Weld. Wood Weld has also been extremely handy on the boat, but the Water Weld gets an extra thank you for literally saving my boat. My home. And all the stuff that's in it. Thanks! :)

I was skeptical about this working, but it was the only thing I found that may fix a crack in a fiberglass tub, so I figured I would try it before replacing the tub. It was easy to apply and so far is working perfectly.

Fantastic product fix my signs 99 4Runner rear heater line with this stuff. It's super sticky imagine playing with super glue in a putty form so have something to scrape it off into place good it will come back off on your finger when you're trying to put it on. Been about a month so far so good.

Dries hard as a rock but doesn't stick to applied surfaces. It rather wants to stick to your fingers. It took a longer than normal shipping time.

It was used to stem a leak in a pipe that was very difficult to access and repair in a more normal situation. It worked well.

I have a rear end with a stress crack about 1 1/2 “ long that make a oily mess from the leak. I applied this about a week ago. So far the leak has been stopped. No more evidence of gear oil making a mess. The truck has been driving about 3,000 miles so far in the mid to high 90 degrees temperatures

Strong work very well

Didn't fix my pvc leak. Product was clumpy and so likely didn't fit flush into leaking crack.
