Review on Butyl Rubber Waterproof Tape 4” X 50’ (White/Gray) - Weatherproof RV, Roof Window Sealant, Flashing, Seam, Surface Crack, Pipe Rupture, Boat Sealing by Michael Boyle

Revainrating 5 out of 5

Delivered quickly, easy to use

This is my first time using this material. It seems to work. I used it as recommended by Grand Design to install a Winegard Cellular/Wi-Fi antenna on the roof of our caravan. This is the first layer between the antenna legs and the roof. Mounting screws are driven through the tape and a self-leveling sealant is then applied over the entire surface. When it works as designed, there are no leaks!

Pros
  • Perfect for outdoor activities
Cons
  • Upgrades
