Review on Waterproof Kitchen and Bathroom Adhesive Sealant Tapes: Enhancing Tapes, Adhesives, and Sealants for Optimal Performance by Ken Coste

Protective film is not completely torn off. When it came loose and I stuck the tape, the spots didn't stick. After removing and inspecting, I saw that a strip of clear material had come loose from the white backing. This clear material covered the adhesive on the tape so it didn't stick to those spots. I had to find this almost invisible material with a very sticky adhesive and try to remove it. I ended up uninstalling it and using the product. In hindsight, I would choose a different product that hopefully doesn't require messy, messy removal and reapplication. Such a simple product should simply be thrown away. Not this product.
