## Customer Reviews

### ⭐⭐⭐⭐⭐ This stuff works like a champ!
*by H***Y on August 13, 2021*

I sealed up a 2016 Freightliner Cascadia. The truck was leaking between cab and roof. It's a on going problem with this cheaply built truck. Sealed it up good. Taped the seam up put sealer in seam pulled tape after set for 1hour.

### ⭐⭐⭐⭐⭐ Great Quality Sealer
*by W***T on April 6, 2021*

I have used a lot of sealers, caulking and adhesives, but nothing that works as well as this stuff. It turns into a durable rubber when dried, that sticks to whatever it’s applied to. Great quality sealer.

### ⭐⭐⭐⭐ Great stuff, pricey but worth it
*by J***Y on May 26, 2021*

Stuff works great but price is high. I don't mind but customers think it is crazy. They talk about home Depot stuff. Obviously not as good but much cheaper. Lots of people only see price.
