Dr Boat Heavy Duty Repair Kit for Boat Kayak, Canoe, Tent, Inflatables, Swimming Pool, Hot Tub - LIQUID PATCH Resistant to Fresh and Salt Water UV-Resistant Long-lasting - 40ML

After trying the lazy spa patches I was about ready to give up and throw the hottub out because I SUCKED at using those. Fixed one hole, great, fixed second and then the first sprung again.In a last ditch effort I hunted Amazon for anything else that could help and found this stuff. It's so easy to use that even this idiot didn't get it wrong. Super gloopy and it's a surprisingly small tube BUT it is so worth the money.It fixed the two holes we had and then we found a third and it's fixed that one right up too.It doesn't look pretty but honestly I couldn't give a monkey about that. I also got it on my fingers and it was really easy to wash off. Honestly very impressed with this stuff!Will definitely use again in the future. I just searched on YouTube before using it to check I was doing it right as the instructions on the box aren't a great translation.

I didn't believe this would work. Tiny pinhole in my fairly pricey inflateable bed and I thought I may as well try repair before binning it, but had very little faith. But it worked like a dream and the bed has been used many times since, and no sign of failure. Brilliant stuff.

Was cautious of using it. But actually it worked really well. It’s very “gloopy”. Used it in a small hole on a blow up kayak. It took 12-24hoira to fully dry and seal. Being inpatient I expected immediate effort. But I left it outside for 1 day, and it was fully secured. I made a poor cosmetic job but that’s on me. Very much recommend this product.

Was sceptical but sure enough it sealed the hot tub no probs..

Absolutely amazing stuff! Fixed 3 punctures in my hot tub. Inflated the tub and applied over the puncture left to dry and it's perfect!

Out of date glue. Doesn't work! Used the product as described on the tube. Once it's dried and you peel the residue off it rips through all the glue making the hole much worse. I want a refund! Waste of time

We sadly had a puncture appear in our double blow up airbed, so started to look for a repair option, thinking it would be a patch.I had never heard of this product before but after reading the reviews and comparing them to the standard patch repair kits I was familiar with decided on this product.Application was very easy and allowed me to achieve a reasonably smooth appearance, so it’s not very noticeable at all. Followed the instructions and it dried an off white colour on our airbed. Tested and fully repaired so really happy. Time will tell on longevity, but have to say it appears a robust repair so very hopeful.

Used nearly the whole tube on 3 very small holes on my hot tub. Had to re apply 3 times and I can still hear a small leak. Had to use a patch as well on the hot tub but the lid did work fine after the 3 goes
