### ⭐⭐⭐⭐⭐ Reliable product.

### ⭐⭐⭐⭐⭐ Awesome stuff
*by J***K on 25 April 2026*

I’ve used this for years. True story: I have a 40 gallon trash can that is rain barrel. I noted that it always leaked down to specific point. A quick investigation and found a small hole at the level where the water was dropping down to. The hole was about the size of a pencil lead. I sprayed the hole with this stuff and it sealed the leak. That was 4 years ago and it is still holding water.
