## Questions & Answers

**Q: Will it fix a leak on the roof of my RV in the rain**
A: Many people have had success using Flex Tape to repair the roof of their RV in the rain.

**Q: Can the 8" tape be cut in half to use?**
A: Many people have found great success at cutting Flex Tape to a desired size. Leave the backing on tape and cut to desired dimension. Use high quality scissors or razor blade when cutting. We do offer a 4" x 5' tape as well.

**Q: Would this work on a hole I have in my 96 gallon trash can lid that has hail damage?**
A: It sticks pretty well. Its like ducktape with silicone on the back. If its just to cover then maybe. If its to be sealed from water then no. If the holes are small it might be worth a try

### ⭐⭐⭐⭐⭐ Very sticky, have to be careful to put directly on whatever you’re wanting to use it for.

### ⭐⭐⭐⭐⭐ Works better than I thought! Great product

### ⭐⭐⭐⭐ Tape holds fine unless fully soaked
*by S***T on September 22, 2026*

This tape sits at our shop front desk for quick fixes. I grabbed it when a hose fitting under the bathroom sink started dripping during business hours. It stuck fast on the dry section and stopped the drip enough so I could finish with customers. That part was good. When I tried using it on a joint that sat under water in a bucket overnight, the edge started lifting the next day. So for constant submersion, it is not great. For quick, slightly damp repairs and short-term leaks around the store, it works well enough.
