## Customer Reviews

### ⭐⭐⭐⭐⭐ Nice stuff! Reasonably priced!
*by M***. on June 4, 2025*

Very Impressed! This is nice stuff!

### ⭐⭐⭐⭐⭐ Very good adhesive
*by W***S on May 7, 2025*

I've only placed a few pieces so far. However this stuff is super sticky. You will not have to worry about it falling off, just clean surfaces prior to placing.

### ⭐⭐⭐⭐ 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.
