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.

Not Actually "Food-Grade", I'd Say. :/
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.

Needed to reattach a rubber corner bumper of a glass cutting board. Worked well.

Great for Slippers
Are use this on a food chain or that was slipped somehow it sealed it but I’m not sure how durable it will be because the container compresses. However I’ve also but silicone to make nonslip spots under socks and slippers and this is definitely superior for that. The other silicone I’ve gotten gets hard. This stays flexible. Definitely superior to anything else. I’ve tried for this.

Semi-Durable; Impossible to use after initially opened
So I bought this stuff to repair a broken handle on a hook bucket that we use for feeding horses. While I was at it, I sealed up a crack on a cup scoop that we also have. The cup scoop worked out wonderfully and has remained intact and seems to be pretty sturdy. The bucket though, immediately came back apart after curing for 3 days despite putting a pretty hefty amount on it. That’s fine, I mean a horse shoving their face into a bucket that has 4lbs of food in it is a pretty decent amount of force You’d better use all of it that first time that you open it though, because the narrow nozzle that it comes with does NOT come with a cap. If you take the nozzle off, you lose the silicone that’s caked up in the nozzle and it will dry there, rendering the nozzle useless. But it turns out that it will be pretty useless even if you keep it on because…. It still dries. I have been mashing and smashing and trying to prick a hole in on this tube for days now trying to use it a second time, and it finally ruptured out the back end where I had it creased over. I guess I will just be cutting a new hole in it each time I need to use some because when it dries, it will seal the hole back up!

Food Safe, Easy to use, make a good waterproof seal where you need it.
This is a great product for what its used for. The design of the nozzle made it easy to decide how big you want your bead to be. It functioned well, as I could accurately place the product where I needed it. It provided the water resistance I needed, and fixed my issue with my coffee maker. I definitely will buy this again in the future, not only for the seal ability, but also that it is a food safe product.
