[QUOTE="Rudy, post: 4588047, member: 568035"] I agree with this. Butyl describes a wide range of compounds. I wouldn't say "tar-like", just because those words imply asphalt, but there is no question that V-Max and Damplifier use very high quality adhesives, Dynamat Xtreme seems to be lower quality and RAAMmat lower quality still. All should be adequately reliable, but elasticity is important for damping and the further you go down the quality scale, these product's adhesives get less elastic and more gooey. RAAMmat's foil is also somewhat thinner. Everything points to performance being impacted by all of these characteristics. [/QUOTE]
