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.

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.

Great product for the price
Model: 197mil 31 sqft Car Sound Deadening Mat, Model: 197mil 31 sqft Car Sound Deadening Mat
This sound deading material has a good thickness to it. It seems like the cab of the truck is cooler inside from the heat of the motor. It’s easy to install and easy to cut with a razor blade. The quality it’s an 8/10 the only complaint I have is the adhesion will stick to your fingers if you are touching it when you peel the backing paper off. It stick to the truck great tho. It covered the entire floor and back wall of a single cab truck.
