Excellent. Patched my pool with water flowing out of the side.

We used this to get the suction cups of a bath toy to stick to textured walls. I'm sure there will be damage to the walls if we tried to remove them, but we aren't concerned with that. It's held up well through many baths, I can't say how it would hold up to being pulled on with force, my kids were warned to not test it.

I have a pair of expensive Gore-Tex hiking boots that is about ten years old but had seen little use. I put them on during a recent winter storm and after walking about 50 feet the sole of the right boot fell off — didn’t come loose, but stayed behind on the ground when I took a step. I started looking for a strong but flexible glue to reattach the sole and came across this product. The glue is thick and not runny, which made it easy to apply it to the rib structure on the inside of the sole. Because the instructions say that full strength is not achieved until one week after application I let the boot sit that long. So far the the glued-on sole is holding up great and except for a few areas where white bits of glue are visible due to carelessness on my part during the application, you cannot tell that the boot was repaired.

I used this to fix my inflatable hot tub to seal the gasket for the « bubbles ». While it was a bit messy to apply, it cured in 24 hours and I can enjoy a nice soak again. The tube doesn’t have a nozzle tip which would make the process easier for underwater applications.

Overall works great, applied under water (repaired boat lift tube with minor leak, boat lift tube under air pressure thus difficult for sealant to grap hold, in time it worked). Dificult to squeeze sealant from tube, no regret.

Great product. Thank you!

Maybe I just got a bad batch but it has the consistency of elmers school glue that's been left out for too long it's just regular glue with a skin on it. It also does not dry instantly at all it stays in its weird semi wet gluey state for hours which makes it useless for quickly bonding anything. Avoid it if you can help it.

Disappointed in this product. Says for underwater use and it worked for about 2 days before they came loose. So adhesive underwater anyway isn’t worthy.
