Actually seen a guy use it and it worked way back. I don't know how long it lasted though.
Lol, Sealed a leaking birdbath and this cracked reservoir up with the spray. It worked but they needed several heavy coats ..…. View attachment 1715260360
When I was doing plumbing a buddy bought a can of it. To test it I put a hole in a plastic water bottle and sprayed it. Filled it up and it still leaked.
