Flex seal works good for leaky roofs if you can find the spot where it is leaking. I would of given a 5 star rating but shipping was slow and can was dented and bottom of can bulged out a little, although contents was allright.

The commercial said it was safe to use in ponds. I used it and it killed 45 fish. It did not even seal the leaks, I picture looks like it is going to be a big can; It is tiny. I has to use three cans on one leak, and it did not work.
