This is pretty much brand new, I used a little to try out on my old car and now I don’t want it. Sound Dampening Kit; Xtreme; Trunk Kit; 0.060 Inch Thick Butyl with 0.004 Inch Thick Aluminum Face; 32 Inch Length x 18 Inch Width; 5 Sheets; Self-Adhesive For clear, crisp bass without the rattle, use the Dynamat Trunk Kit. Adding Dynamat to the vehicle especially the trunk results in higher Sound Pressure Level (SPL). Dynamat is the easiest to apply, thinnest and lightest material for adding sound pressure reinforcement to your cars body. When the panels dont rattle and balloon, you get higher SPL and tighter, louder bass! https://www.partsengine.ca/19405-vp-dynamat-1427.aspx?gad_source=1&gclid=CjwKCAjwhIS0BhBqEiwADAUhc5jNA0q4G1O2gVKodoF0T5VoVdzJd-nS8PTiOCpifBcDXEeOvx78wxoCI9oQAvD_BwE
