Review: Works great! - I bought a Black and decker juicer for a friend and his grandkids broke the basin that holds the juice. i purchased this to repair the basin so it would hold liquids again. It is food safe and it worked. Great product!
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.
