actually surprised how great the product is and way better priced then other companies. its sticky and also has thickness enough to cover metal parts on cars. i would recommend 100% just ordered another 18ft for the rear deck and to have some extra! does not smell. easy to install and helps stop vibration.

I have it under the closed cell foam. It’s great. Just as great as Killmat and all the other butyl rubber products. Let me ask you to do something: look at the people who rated it 1 and 2 stars. No reviews. No pictures. Why? They don’t want to see the most budget friendly product getting sold. That’s some weak business. Rest assured you’ll be happy with this. Why did I buy both types? Butyl rubber helps the car not be a tin can. It keeps the outside road vibrations out. Closed cell phone keeps your music in. They work best together., Kumbaya, we have unity! We can get along, even in this age in time. The closed cell foam is cheap. You’ll get it to replace the nasty cloth under your carpet. Do the knock test. It won’t help. You need this too. And truth be told, I prefer that it has no name on it. I’m not paying money so you can brand yourself on my car. Ps: these products go on and don’t come off. Don’t mess up. It’s the same for the competitors and the closed cell foam. One shot. Do it right the first time. I’m writing this review after I used up my first box and am getting more. Happy returning customer.
