sound deadening material??? are names worth it?

[severous01]

i'm looking over on sonicelectronix.com and there's a ton of different materials in different thicknesses, and a million different prices.

i'm thinking about this:

i like the fact that it's aluminum faced and self stick (which most of them are just butyl rubber...good for insulating sound and temps), and it's cheap...and it's got free shipping when everything else is 35 bux to ship. it's the same material as dynamat, weighs less, has the thermal barriers, and comes in perfect length/width cuts already. i hate cutting butyl...it's so dang sticky it'd stick to a teflon skillet. any way, i just want to do the firewall, floor, trunk and roof of my HB. i'll do the doors when i do speakers, but for now....road noise is killer. and it's coming from the wheel wells.

any way, just looking for some experienced users of sound deadening stuff. is dynamat worth the name's price vs similar products?


this is nice too...even cheaper:
