I made the mistake of leaning my inflatable boat up against the RV and the heater exhaust burnt a hole in the removable seat (fortunately, not the main boat). It was a pretty substantial area that was weakened and the main hole was the size of a coin. I had my doubts, but this glue repaired the hole and it held fine.

Like seemingly every air mattress in the world, ours sprung a leak. I was about to order a new one, but decided that I would see if I could actually find the leak and fix it.I pumped up the air mattress to a "very full" level and then started feeling around for the hole. It took a few mins, but I eventually found it by just running my hand over the mattress. Didn't feel like messing with soapy water, so I was glad it worked out this way.It was a pair of small holes that looked suspiciously like they came from the cat, but he swears he didn't do it. I probably didn't need to, but I patched mine in two passes. On the first pass, with the mattress much more loosely inflated (but the spot with the holes not touching any other part of the mattress inside), I sqeezed a little bit of the glue into each hole to give it a chance to bond itself back together a bit. I let that sit overnight. There wasn't enough pressure inside the mattress to blow the glue out, just enough to keep me from gluing the hole area to another part of the mattress.About 24 hours later, I did more like the instructions said. I cut one of the patches to size, spread glue on it, and adhered it to the now-deflated mattress. I set a weight on it (I used a 10 pound kettlebell that wasn't serving any other useful purpose) and let that sit another 24 hours.Worked like a champ. The mattress held up great for the 5 nights that I needed it to, so this wound up being substantially cheaper than buying a new mattress!

Seems to be good so far

Excellent product. Make sure you use as directed and leave it for the full 24 hours it takes to set. I inflated the mattress and let it sit for 3 days. No air loss.

Did not work out for us patched holes in infatuated hot tub .
