Second Skin FTWFW hands down. No questions asked. best you can buy. THE BEST.There's a website somewere showing its heat resistance and thermal insulation abilities and acoustil deading. Or something like that. Any way. its the best.
I do respect your opinion and have used a number of SS products, but until they can qualify and quantify their results with some sort of test data, then your statement is just a matter of opinion, not fact. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
For the majority of most car audio dudes, the "best" is the highest performing product for the money. It seems Damplifier Pro, Dynamat Extreme, and VMax are the highest performing "deadeners" on the forum as they have none or very few complaints from users. They cost more because they are made from higher quality materials (for the most part.)
It seems RAAMmat has had some inconsistencies over it's evolution which may attract criticism. For me, it was very tar-like to work with and I'm not sure why a true butylene rubber product would have this. DE is also slightly toward this end IME as well. After a couple years on my doors the butyl has gone slightly gooey, but still has maintained it's overall integrity. DE and VMax, on the other hand, have remained just as they went down.
I think this is all relavant because in order for a VE damping product to work, it must maintain a VE bond to the surface. I don't know how the damping performance changes if the damping layer goes bad, but I can't imagine that it would improve. That said, there are many so called "sound deadeners" on the market that make bogus claims that aren't worth it in the long run. It seems PRICE is the best way to spot an effective VE deadener, really.
