### ⭐⭐⭐⭐⭐ heat blockinf and noise reducing
*by T***G on June 19, 2025*

used on the roof of my 23 forte. has helped with the Texas sun on blocking out heat along with heeping my ac cool.verry stick no smell. help with redusing vibrations from my subs. light weight and easy to apply. it will stick to what ever you put it on so dnt drop it lol

### ⭐⭐⭐⭐⭐ Bonds the instant you peel the wrapper
*by J***1 on June 11, 2025*

Extremely sticky and good heft. Once they go on they’re not coming off. 4 mil is accurate. Highway noise is much reduced in a tall Sprinter van. I still have a lot left over so I’d say it’s a good value and size.

### ⭐⭐⭐⭐ Once placed, cannot be adjusted
*by M***E on April 22, 2025*

Very difficult to use. I tried to use this on the inside roof of a 71 Plymouth which has a lot of stiffeners and recessed supports. I've used a lot of the three in one Silas sells, and it is a little forgiving if you need to adjust the placement and haven't pressed it in place yet. This stuff does not!Once you lightly place it, it's stuck. When you pull it off, the foam layer stays behind and must be scraped off.Works great for simple surfaces. If you need to slide it under other structures like stiffeners, find something else.
