Dynamat 10455 18" x 32" x 0.067" Thick Self-Adhesive Sound Deadener with Xtreme Bulk Pack, (Set of 9)

Dynamat 10450 five I've had the Dynamat installed in my four subaru impreza back sport for about a month now in it as well worth the effort when I say effort I tore out my entire interior to install this stuff inner and outer door skins entire floor doubles up in places trunk doubled up again for your hatch and under my hood it took a total of about 17 hours to install and trash my hands cuts in sore for several days I used the Dynamat heavy-duty roller for most of the installation into the handle of the roller to push the material into tight criticizes my entire car excluding the roof just 2 and 3/4 full pack myself have some leftover and trying to figure out what to do with it the results you could say I was skeptical like other users mostly because I hadn't known anyone who use it or what Dynamat was even made of really it's basically sheets of tarp butyl rubber back woods thick alum
