Review: Sealed a crack on the bottom of 3 gal plastic container holding liquid. Seal is solid. - I dropped a container that I use a lot and it got a dent in it that included a tiny crack. I needed a food safe glue to cover the crack. This Food Contact Safe sealant worked perfectly. The container holds 3 gallons of water. The glue has held up well and the container is functioning as it should again. The cost of this glue is worth it, considering it saved me money not having to purchase a second container. The instructions are clear and easy to follow. Adding the sealant was quick and didn't require a rocket science degree. It is one application and no mixing. Yes, it has a little smell, but it dissipated quickly and you cannot smell it after a few minutes.
Review: Worked great - Good product. I would buy again.

### ⭐⭐⭐⭐⭐ Sealed a crack on the bottom of 3 gal plastic container holding liquid. Seal is solid.
*by D***S on October 24, 2025*

### ⭐⭐⭐⭐⭐ Worked great
*by B***. on January 2, 2026*

Good product. I would buy again.

### ⭐⭐⭐⭐ Not Actually "Food-Grade", I'd Say. :/
*by D***. on January 4, 2026*

It worked well, but I don't think it is actually "food-grade", as it claims to be. I fixed a cold-brew, stainless-steel filter with it but the coffee tasted like the silicone smelled, even after several washings & attempts. (The filter is trash, now.) :( Also, the tube of silicone came with a small puncture in it! I repaired it with some of the silicone, however, rather than returning it & waiting for new to arrive.
