Review: Perfect fix for deteriorated in ground pool liner - Had UV damaged to border on pool. Small holes were appearing. Trying to get another year out of 13 year old liner. This tape worked great. Used rubbing alcohol to clean border area. Adhered to liner very well. Recommend this product.
Review: Very sticky and thick. I believe it’s worth it. - Very sticky so be careful. Can’t say how long it lasts but if it lasts like it sticks it should work fine.

## Questions & Answers

**Q: What is the holding power or tensile strength like? Looking to patch a load bearing torn seam on my heavy spa cover where it folds in half**
A: Doubt this is what you are looking for

**Q: Will this seal a small hole on an alluminum boat**
A: It would but I don’t know that it would be a good long term solution. I have used a product called Mr Sticky on an aluminum boat and it worked really well

**Q: Would this work in a shower tub seam**
A: Might not look as smooth as caulk but it'll certainly do the job.

**Q: Can this be applied under water?**
A: I don't know about applying under water, but it is good to keep water out.  I had water coming into my basement from a crack in my patio.  Put flex tape over the cement crack outside and haven't had any more water seep into the basement and hasn't for several years.  Not that pretty, but it works!

### ⭐⭐⭐⭐⭐ Love it
*by R***M on February 16, 2024*

This tape is fabulous for rv roof repair. Had to make roof repairs on two different RVs and it was easy to install and worked great. Put down new roof membranes that did not seal well at the edges of the roof. This Flex Tape sealed the whole roof on all seams and edges first try. Great stuff.
