Just purchased this to fix a couple holes in my above ground pool and it works! I patched one hole that was on the bottom and about 10mm long and it adhered underwater! Underwater! Amazed at how it does what the ad says. The other was patched from the outside and leaking water at time of adhesion and is still holding. I love that it is flexible too, so it contours to curves as well! Brilliant stuff!

Very happy with flex tape. Easy to use, applied reasonably easily. Appears to stay in place well, we are using on shower wall, has been in place for just over two weeks.

The tv ad is misleading in my opinion with regards to being able to use under water I tried to seal a hole in my in ground pool and it just wouldn’t stay on , I have used it on a plastic pipe and it work fine but as for under water it failed
