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.

Had a tear at a corner seam on in inflatable kayak section that was impossible to repair with regular patches and glue.This worked perfectly and has repired a 1 inch long tear and holding up well.Applies easily and dries quickly into a nice vinyl patch that flexes enough despite being quite sturdy.Air tight and no leaks whatsoever.Slightly overpriced in my opinion but you could do many repairs so depending on use could be decent value for some.I also used it to assist repair of a broken piece of plastic that covers the engine in my car and has worked fine with a combo of glue.

Amazing stuff!!Bought to repair a small tear in my inflatable hot tub. I had tried the glue that came with the repair kit, but the patch wouldn’t hold.A quick squeeze of this stuff and the patch held!Now fully inflated without any need to top up

Terrible. Had a very small puncture in a kayak. Put this on and followed the instructions. Then pumped the kayak up and it ripper the hole making it 10 times larger. The product cant deal with the pressure and sticks to the kayak causing it to rip more. Avoid.

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

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
