## Customer Reviews

### ⭐⭐⭐⭐⭐ Works great!
*by T***A on February 24, 2025*

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.

### ⭐⭐⭐⭐⭐ Easy to use
*by M***K on March 16, 2025*

Easy to use and works as advertised

### ⭐⭐⭐⭐⭐ Super happy and worth the cost.
*by T***E on April 5, 2025*

Wow, super strong! I needed this for my Mercedes-Benz overhead structural beams that the factory missed, and glue them onto thr van’s ceiling. Perfect. The vibrations and rattles went away. I had an extremely thin space to get this into, so it isn’t always pretty in that situation. But dang, worked exactly as we needed. Super happy and worth the cost.
