Unbelievable, water resistant, clear, long lasting glue works on any surface
This sealant/glue is amazing. During the rain my metal porch roof had a crack in it. I dried it off as best I could and put this amazing glue in the crack like magic. The roof stopped leaking. It dries quickly, it is water resistant and it is the best quality glue around. It is also clear; so you can put it on different surfaces. I saw the spectrum technician use it when he came over to fix a leak. The price is amazing. It saved me hundreds of dollars in repairs.

Very Satisfying!
It fixed a broken sealant valve that was leaking on my Delonghi coffee maker which would have cost $1500 to replace. Then it fixed an old 10-gallon water jug that was falling apart and threw $5 plastic laundry baskets. I still have have a tube left and I wish I had more broken things to fix. I heard about this product on the No Agenda Podcast that ends each episode with a tip of the day from John C Dvorak. Thank you!

Works well. No leaks
Just what I needed to reassemble my countertop ice maker gearbox. I let it cure for 24 hours and nothing leaked

Great! Air-tight cap for many uses!
Great stuff, and most importantly the cap seems to really keep it airtight! So I can use it for numerous small jobs.

Seal your Ninja products!
I have a few new ninja products that are for food preparation. One is the ninja slushi and the other is for ice cream. Both have designed flaws that allow food to get into the crevices of the canisters that hold them. This product was recommended by another ninja purchaser., and it worked well for them, so I tried it. It’s sealed up the tiny creases in the product that were a designed flaw prior to my using these items.. this will keep my food safe from contaminants that cannot be removed, will allow for ease of cleaning of the product, and was easy to apply. This made the purchase of this silicone much more valuable than it’s low cost. It’s hard to put a price on your health. I’m going to recommend it to other ninja product purchasers in the various groups where we share recipes. Thank you to the seller for the prompt service., good packaging, and wonderful product

I was looking for a food grade silicone that I could use to repair a cracked plastic waterer for my chickens. I really didn't want to have to buy a new one (approx $80) so I figured what did I have to lose by using this $11 tube? According to directions, I cleaned the area, wiped it down well, and applied the silicone to kind of sandwich a piece of plastic to the outside of where the hole was (about a loonie in size) and applied the silicone to the inside and outside. I left it to dry about 24 hours. The next day I was fully ready to be disappointed but to my luck it held 3 gallons of water perfectly with no leaks!!! This stuff is amazing and you get so much product in the tube. I would 100% recommend.
