Yeah this stuff is good for leaks

I tried to seal up my water tank in the toilet..due to a small crack leakage..I pure this item in the tank..it did its thing to fill up the bottom and 2 days later it harden up like silicone but once the water got to it, it melted like egg whites.. The solutions broke down..This product Not waterproof..Not Good at all .

Great

Not enough to really use on anything

Seems to work OK but the brush is too small for larger applications. I used it to seal my pond lining. I will have to see how it hold up over the winter.

We used this on the roof of my vehicle as it began to leak, and although I was skeptical, It completely resolved the problem! The instructions were easy to follow, and it worked like a charm!! I definitely recommend this product.

The leak can't be leaking to use this. My shutoff valve had a very small leak, so I tried to fix it using this. I have tried to apply this, so far, 4 times. It is not holding the water out. I did not want to turn the water off, at this time. I will try it again tomorrow, turning the water off this time. This might be good for sealing pipes prior to having water run through them.

I used this to try and seal a small crack on my front steps that a contractor told me would get worse. I know I know. But hey - if I have to replace the whole thing anyway I'm going to try and delay it as much as possible! It's like a thick whiteish goo that dries mostly clear but a bit of a haze. It's not slippery which is super nice. We'll see how long it lasts but it's working so far!
