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.

Lol, Ya' sound a bit skeptical there doogievlg.
All the blackened lines inside are the cracks. The liquid level is at the top white camera flash reflection.....

No leaks under it and it's oil based...……..
