Works well
Size: 10 sqft
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.
