## Questions & Answers

**Q: How well does this adhere to a leak on a liner bottom with a pool full of water**
A: I used to to wrap around styrofoam dock floats in the lake.  The ones I did early in the morning didn’t adhere as well as the ones I did late in the sunny afternoon.  They have been in plCE FOR ABOUT 6 months now and doing well.

**Q: is it usable for roof ridge already covered with flex seal?**
A: Maybe use a larger piece. I haven’t had it fail on anything I have tried it on yet!

This may be expensive, but it’s worth every penny. Patched a section of garage roof. I actually think it will outlast the shingles.
