I wish these were sold in mini mini containers. Once it was opened - its life was over. Used 1 ounce and 15 ounces dried up. I sealed it back up with a pliers and put it in 2 plastic zipped bags. 1 month later it was rock hard. It work on the inflatable and sealed it well. I sold the inflatable less than a year later, so not sure if it held up.

Used it to adhere and mend clear and smoke plastic windows for pop up camper. Just small patches and wasn’t worried about it being cloudy or not. Help up to high winds and torrential rain… Will see how it holds to cold and snow.

I bought this product to fix the doors on my Mercury Mariner 2006. All of the vinyls on the 4 doors have fall off due to the foam between the vinyl and the plastic on the door been 10 years old. I try many products sold by Lowes and Home Depot, like contact cement, 3M products etc., but due to the roughness of the plastic on the doors none of them adhered, and the ones that did, after a couple of week under the intense heat of Texas weather, the vinyl peel off again. The Instructions on this product said that you need to apply the HH-66 on both surface and let it dry between 2 to 5 min. which for this application I found that was not enough time to make it work, at the beginning I was I little bit disappointed with it, but after a couple of tries, I found the right combination on the amount and time and cannot be happier with the result. So far, it’s been more than a month and the doors looks like new. But I need to make the comment that you need to be really precise putting both parts together, because one they touch each other, you are done, they will stick together and it will be really hard if not impossible to remove without damaging the vinyl piece. The attached image is of the final product, I highly recommend this product.

The cement has so far worked well in patching my pool. I searched for videos for underwater application, What I found was not totally workable. Following directions, I placed the cement on my patch and folded it in half. Underwater, I opened it up and placed it in position. It did not adhere completely to the wall of my pool. I had to hold it in place for a while to get the main body of the patch to stick. Unfortunately the edges did not seal to the pool wall. I took the dauber, loaded it with cement, slipped it underwater and 'jambed' it around the edge. I had to do this all the way around the patch. I was able to successfully seal the patch. A month later, my pool is holding water. This product works well, even under water, but requires a bit of extra effort to be successful. A small patch above the water level adhered without any problems.

Easy to use. Strong hold, and didnt seem to take very much. Would definitely buy again.

I bought this adhesive to fix large 132 gallon vinyl rain barrels. The hot-pressed seal line expanded under water pressure. The opening are either hairline, pin hole up to about 1 mm, or crack line no more than 1/4 inch by 1/32 of an inch. I applied 2 coats from both inside and outside (one each time then let it dry fully for 2 days at temp >60 deg F). It works well afterward. For larger rip, an addition piece of vinyl is required. Cut the patch to cover at least 1/4" to 1/2" from the nearest edge of the rip. Then apply the adhesive to the patch, wait for a few seconds (longer if you're doing this at temp below 50 deg F and immediately if you're doing this in 80-90 deg temp), and press the patch onto the hole. Let it dry in open space. Follow the manufacturer's safety guidelines on the can. Do this out in the open, well ventilated space away from any potential ignition sources. Avoid inhaling while using it.

I had to repair an Intex explorer inflatable kayak. It had a small hole that I cut bigger to try to fix using fancy gorilla tape (worked for a little while, but was bubbling and obviously not a permanent fix), but that didn't work. So, I followed the instructions carefully, cut out a piece of extra raft vinyl, and used this to seal it. I then kayaked 8 miles of the Colorado River in the cold, and it held beautifully (all of my other patch attempts had not held air). It looks nice and permanent. Hopefully it holds for many more seasons---now I have enough to patch many more holes that are bound to happen on that kayak and several others I have for others to enjoy.

If you have an inflatable boat that’s made of HEPA lawn or vinyl I highly recommend this product for patching and adding additional attachments
