No complaints. Seals very quickly.

I have a 9 foot dinghy for my sailboat. I bought two bottles. I wanted to use one to fix it and save one for later in case I needed it. FIRST TRY: I read the instructions carefully and followed the directions by removing the inflation valve and squeezed all of the liquid into the front chamber, replaced the valve and began moving the dinghy around every which way yo coat the innards with the liquid. Fingers crossed but the next day it was flat. SECOND TRY: I came back a week later, located the pinhole (which was very small) with soapy water and used my second bottle. This time I knew where the hole was so I focused my efforts moving the dinghy around to make sure that the liquid got to the area where I found the hole. I even saw very little blue liquid come out of the hole so I knew it got to the right place. The next day it was still inflated. YAY! NOT SO FAST... The next week when I came to the boat it was deflated again. Now what?

I didn’t have too much luck with this one - If you are going to try for larger inflatables, I suggest NOT trying to split the bottle - The bottles contain a liquid and a small kind of sealing material that would make it hard to split evenly - Make sure the top is cut enough and that you shake the bottle enough so that the entire contents come out - (Make SURE your tubes are DRY inside!) - I think think this may have done well for small scale or with larger amounts, but didn’t work well enough for me when using one bottle per tube in dinghy

WARNING ⚠ Do not use this product on your Bote board. It destroyed my board. Within minutes of using this product I could hear popping inside the board and then big bubbles started to appear. Wish I could upload photos but would except my format. Beyond pissed now. Worst product ever. Now out $1800.

The product was didn’t seem thick enough? We sealed one side with a didn’t product and it worked, wanted to try this one product but didn’t, kinda disappointed.
