Good stuff
Size: 50 sqft, Size: 50 sqft
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.

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
Size: 20 sqft
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.

Excellent product high quality.

This stuff definitely suprised how easy it was to work with. Not to mention it sticks very well. Don't put it on anything you may need to get back into. It will take the paint off of a service area. I have a 2018 dodge durango. I just had a aftermarket audio sytem installed. It was rattling so bad it was driving me crazy. I seen this stuff and decided to give it a try. Its a night and day difference no moore rattling. I box will be enough to do my back gate and all front and rear doors also. For the price you honestly can not beat it. If your on the fence about trying it don't be. You definitely won't regret getting it. Its worth every penny. You don't realize how much something rattling in your vehicle robs you of spund quality. Glad I made the decision. Now off to the other 4 doors. ,and then the roof. One of the things I really like was the fact it has multiple line to help you make even better cuts. Definitely will buy a gen.
