## Customer Reviews

### ⭐⭐⭐⭐⭐ It is sticky!
*by T***G on May 30, 2022*

I used this to replace the missing insulation between my truck’s interior door panel and the door. Like the manufacturer and many previous reviewers have said, this stuff is VERY STICKY. Having read the reviews, I had a few ideas about how to work with it. Here’s what I found to be most helpful:1. Pre-cut your material, so you’re not working with the excess.2. Once you have the material cut and positioned where you want to use it, pick a corner and peel back just enough the backing to stick the corner or edge to your surface.3. Applying pressure as you go, peel and secure in small sections.This produced excellence results for me. I was able to apply almost a complete sheet of insulation without getting it all over my hands or having it adhere to places where I didn’t want it. I hope these tips help!The road noise dampening is really good. I’m sure the material will become fragile and more susceptible to rips or tears when it ages, but I’m not planning on pulling my door panels a lot. If you’re careful in your planning, you can even separate the backing you want to retain (like covering the open spaces in a door) from the backing you want to remove so when you pull the backing sheet, it will leave the backing that you want to keep, so you don’t have interior components (like power window cables) sticking to the insulation adhesive, which is VERY STICKY (repetition for emphasis. No joke. It’s super sticky!)

### ⭐⭐⭐⭐⭐ Great product
*by G***Y on February 7, 2025*

This looks great and was the prefect amount to do the trunk in my 79 Malibu

### ⭐⭐⭐⭐ Good item
*by S***B on April 23, 2024*

Cheaper than Dynamat and works to get vibrations down, mine arrived with damaged packaging so if you need large sheets intact maybe purchase elsewhere but in my case I needed small patches and the damage didn't matter.
