CANOPUS Sound Deadening Mat for Cars, 50 mil 36 sqft, Pack of 18 Sheets, Butyl Sound Deadener Mat, Audio Car Sound Dampening Material for Car Trunk, Door, Floor and Ceiling, Black

Great product. Very good adhesion and it’s really thick material. Installed it on my 2022 Polaris RZR doors and roof, which significantly cut down on noise and heat. I used 21 sheets total to do the entire project. Will be using the rest to do the interior of my truck next. Highly recommend.

Nice product , works as advertised and is made in America !

Great stuff for the money. Takes the rattle out of an old truck's door panels. Easy to work with and sticks well.

After installation I wiped down with isopropyl alcohol to prep for the next layer and the black paint came right off. If you are going to put anything on top of this product get the plain silver version.

Excellent product. Applies easily and really sticks. Definitely an improvement in deadening the door panels in my truck. Highly recommend.

Got this to help with road noise in my Jeep. Went down so easy with a 2" metal roller. I does Stick to your hands if you stick them where they don't belong, just use goof off and it cleans right up. I would recommend this is you plan on deadening any space that needs it. BTW my Jeep really is much quieter!.

Worked good in my 1971 Chevy truck

Bought this because of some positive reviews I saw on social media. Specifically, holding it in higher regard than kilmat or dynamat. The first thing I noticed was that each sheet was surprisingly light and flimsy. So much so that I doubt it has very good sound dampening abilities. The second thing is what another reviewer pointed out last month - there IS NOT adequate adhesive on the sheets to make them stick well to paneling. All signs point to this being cheap and ineffective. What I received was in all ways inferior to the 80mm kilmat I bought and used a few months ago. Hopefully it was just a defective batch or something, but I'll be returning this for a refund
