Good stuff. I did a lot of work on my 91 Toyota Land Cruiser 3FE. I did the inside and outside doors, as well as the under-hood area, with some extra work. I like this stuff. It sticks down good but you have to clean your surface so there's a good grip. I think these are going to do well for noise cancellation. The deadening material does well with absorbing vibrations too. But the install roller tools it will come in handy. Trust me trying to do it by hand is not worth it.

Works well

Worked great at a budget price. I used it to damp a fiberglass loudspeaker horn. Easy to work with too.

Good material but bites back

Very good product for my rear trunk and backseat on my mustang. I would recommend some type of gloves due to the foil itself when placing down will cut up your hands and fingers. Overall good product for its price.
