Review: Works well. Has strong adhesive backing. - Excellent for waterproofing
Review: Better than electrical tape - We use this for wrapping antenna connections and it is water tight. We recently had to change an antenna and cut the old tape off. The connector was dry as a bone. This is the stuff you need. Stretches tight. Takes a little finesse to get it from creasing over itself and unrolling the plastic at the same time but is excellent. I bought a bunch of these. You will never go back to electrical tape again!

### ⭐⭐⭐⭐ A solid solution
*by M***K on September 2, 2024*

I wound up making a more permanent repair , so I didn’t use this product. This product was exactly as described, appeared solid and fully functional . I opted to do the full repair as a matter of preference. I have no doubt that this product would have done a great job and would have held up nicely. I would recommend this product!
