Review: If your unsure. It's definitely worth it - About this to install a fan in the bathroom of my camper. I instantly tested to see if it was waterproof before I added my Henry's tropicool sealant on top. It worked perfect I left the water hose on the roof with water hitting Butly tape directly no water penetration whatsoever before I even put the screws to tighten it down this stuff is amazing. It's incredibly sticky and the thickness was exactly as described
Review: Good tape adhesive - Used this to resecure a rubber trim piece on our motorhome and it worked perfectly.

### ⭐⭐⭐⭐⭐ Excellent choice
*by E***. on September 26, 2026*

This tape was perfect and should turn out to be durable, it appears to be water resistant as there hasn’t been any evidence of leakage. It is as thick and wide as it should be, and the appearance is spot on for butyl tape.
