Review: It works and it's strong! Heavy duty, but not big and bulky - Happy to have this heavy duty tape ! It makes repairs look neat and clean. Strong and waterproof, but not big bulky and messy looking! My car headlight cover cracked due to a minor crash. This tape did the trick! Provides a strong, protective, water-proof covering that stays in place. The adhesive is strong, but the sticky stuff can get a little messy when on a warm surface, like on the surface of a car, near the engine. A good, strong, clear, protective tape, indeed!!
Review: Super Sticky to patch up cracks and splits - I wanted something to patch my blow up Kayak, the next time it gets a hole. This tape is thick and super durable and super sticky. My first repair was to an outdoor plastic storage box. It had developed a few cracks in the top from weather and abuse. The tape went on nicely, conformed to the curves of the top and it completely sealed the cracks. I know this because there is a slight dip in the top and rain water collects there and the tape does not let it seep through. I see no issues with edges creeping up and the container sits for hours in the sun each day. As for the Kayak, I have not actually done a repair yet as I don't have a current hole, but I know it will work great. I precut some smaller patches from the tape roll so that I can have them ready when deploying my Kayak. Great product. Premium quality.

## Questions & Answers

**Q: Will this tape work to repair a heavy duty polyethylene tarp?**
A: Temporarily, but sufficient movement, dust, etc. will likely cause it to loosen over time.  Consider sealing the edges with”paint on” “flex seal”.

**Q: Will it work on a leaky pipe in the bathroom?**
A: Hi there,
While this tape would work for your situation, for a leaky pipe in the bathroom I would recommend our Powersteel Duct Tape. That tape is some of the strongest tape you'll ever lay your hands on and will clearly up any leaky pipe you have.

Thank you

**Q: Will this stick to rubber?**
A: Hi there,
Thank you for your question. Yes this type of adhesive is meant to stick to most rubber material. We also guarantee all our products so if you were not satisfied we'd offer you a full refund.
Thank you,

**Q: could i use this to protect the joists under my decking?**
A: I used the tape to hold down roof tile until I could replace my roof. I would not think tape would be strong enough to protect deck joists unless you want to keep mold or insects from harming the joists. If you are using the tape for support to with stand a large crowd or heavy loads.  I would replace the joists for safety reasons.

### ⭐⭐⭐⭐ Really great tape!
*by T***E on September 21, 2020*

I used this to patch the liner of an above ground pool. While on vacation, the pool took a trip of its own by flinging itself over a barbed wire fence. It was too late (and too expensive) to buy a new liner so we patched it. There were a few large holes where the pool impaled itself on a t-post plus countless smaller holes. The tape did great on the bigger holes, but so-so on the smaller ones. It seemed that because the pin holes needed smaller pieces of tape, dirt/grit got caught on the edges and worked it's way in, which loosened the tape. While we were filling the pool we were still finding leaks. The tape worked great under water. You have to put a lot of pressure on the tape (I stood on it for about 5 minutes) and it will hold. Bottom line is the tape did work really well considering the job I had it do. I poured over the reviews before I bought it and took into consideration that a lot of people thought you just stuck it on and expected it to work like scotch tape. The only thing I wish is that instructions came in the package. It was a pain having to go to the website for instructions.
