A: Many people have had success using Flex Tape to repair the roof of their RV in the rain.

### ⭐⭐⭐⭐⭐ Very sticky, have to be careful to put directly on whatever you’re wanting to use it for.
*by M***S on August 23, 2026*

Ong did not expect for this to work so good. I had a leak in shower faucet and when I say this stuff sticks and has no leaks. Wow. Definitely a great buy and worth your money.

### ⭐⭐⭐⭐⭐ Works better than I thought! Great product
*by J***N on August 26, 2026*

This product works great for instant repair and has held for months now! Yes I will buy again just to have on hand incase a quick fix is needed. It works on wet surfaces and holds great.

### ⭐⭐⭐⭐ "Fantastic at stopping leaks—just be prepared for a little patience during application!"
*by J***D on July 21, 2026*

⭐⭐⭐⭐☆ This tape definitely does what it's supposed to do—it stopped my leak quickly and created a solid, waterproof seal. Once it's in place, it holds extremely well and gives me confidence that the repair will last. The only reason I'm giving it 4 stars instead of 5 is because it's a little difficult to work with. It's very sticky, which is great once it's applied, but it can be tricky to position and smooth out exactly where you want it. Overall, if you take your time applying it, it's an excellent product that really gets the job done.
