## Questions & Answers

**Q: Can this be used to tape rope onto a raft as a handle?**
A: Thank you for your question! We would not expect the tape to work in this application.

**Q: Will this tape repair tears in a pvc material with polyester reinforcement and uv coating?**
A: Thank you for your question! For best results, assuming the material is not solid, the tape should be applied to both sides (under and over) of the tears; however, we cannot say for certain how well and how long it will hold.

**Q: Can this be used with fish?**
A: Thank you for your question! The waterproof tape is not rated for use with fish tanks/ponds.

**Q: Will this tape completely and long-term repair and seal a leak (3/16" long) on a garden hose, when the hose is connected to high-pressure sprayer?**
A: No. I was disappointed in this product. I purchased this tape to repair a garden hose leak and it did not seal off the leak. I had to replace the hose.

### ⭐⭐⭐⭐⭐ Amazingly sticky.

Stickiest tape ever. Works great.

### ⭐⭐⭐⭐⭐ Adheres well

First roll I purchased would not release the protective paper liner. Called supplier and they sent me a second roll. This roll works well, the protective liner detached from the tape as it should and the tape works well.

### ⭐⭐⭐⭐ Pretty good tape
*by D***. on December 9, 2023*

Does stick but seems to not hold up well with condensation. I’m using this to hold a fish tank light in place ( it’s light weight). I do have to replace every few weeks because it comes loose. Regardless, better than anything else I’ve found!
