Review: Quality product - Works well. Takes a complete tube to do one vent. Apply up the side of the vent a little so you don’t trap water around the vent flashing.
Review: Roof lap sealant - Works great on my recreational vehicle. Make sure and follow the instructions, because it will take a little bit for the sealant to level out to it's final product.

### ⭐⭐⭐⭐⭐ Worked great!
*by K***I on January 14, 2026*

I used this when installing a Starlink on the roof of our motorhome. The cable was laid flat for approximately 25' from the entry point to the antenna. I then covered the cable with spills of this sealant at equal intervals. The sealant settled over the cable and the roof material and hardened. This effectively and confidently attached the cable to the roof without needing to use hardware and penetrate the roof surface.
