Review: Works great! - Was looking for waterproof epoxy, to stop a very small toilet leak. Tried this, Used on hairline crack on bottom of toilet not the toilet bowl or back of toilet but the very bottom part of the toilet where the water travels down the hole when u flush it. On the outside there was a hairline crack and we put this on there and it stopped the leak. Dries in 24hrs, took a while bc the surface was wet, its hard to get the water out of that part of the toilet so it kept leaking while trying to put on the glue, lol.
Review: Good Product - I like this product for several reasons. It dries to an off-white color that is almost an exact duplicate of the boats gel coat. The product dries relatively quickly, leaving a hard finish that can be sanded. The only real complaint I have is that it’s sag when placed on a vertical surface.

Had a leak in our RV sewer line while we were on vacation and needed a quick fix until we got home. This fixed it super quick and held amazingly well. Will definitely recommend.
