I've had good luck with the spray to fix leaking pvc joints. Never tried the tape

I’ve used it with minor things and had luck. There’s a new product called Alien seal spray that’s getting a lot of talk now.

Had a 2nd floor tub that was not installed properly and would constantly leak. After trying a number of different things, my last approach before ripping it out and redoing it was to use flex seal around the space between the tub & surround. Never had an issue with leaks again (did have to pick hair out from time to time).

Tried the flex tape on small holes in my roof after Ida to hold me over until I could get on the roof to put up a new tarp. Slowed down the leaks a little, but mainly just moved them to a slightly different spot. Had I installed properly when it was dry, probably would have worked; but the slap it to the spot definitely did not work and helped me find a few nails.

Tried it on an inflatable pool to hold the kids over until the new one came in last summer. Did not do anything to slow the leaks once it was completely submerged

Their glue is the best thing I’ve found to patch river tubes.

It, along with Great Stuff and Seafoam, is amongst the greatest products I have ever used.

I used it on a roof that had a Parapet Wall, worked great. A friend had a leak, I went up on the roof, did a cleaning, used the Flex Seal, took my time with a couple coats. Never leaked again, a few years later after my repair, they had a roof installed, asked the roofer about the work on the wall. He said whomever did it, did a great job.

I sprayed some in a cracked terra cotta bird bath and it lasted about five years before it started to peel off.

Were you slapping it on hard enough?
