Vette(s): Coupe 74 - 454
Drive it like you stole it!
Hushmat founder himself on youtube.
In this one, he really focus on sound deadening: http://www.youtube.com/watch?v=MYJsJzBz2iM
In this later one, he's more specific about cooling as well: http://www.youtube.com/watch?v=nqb3wdQXLLw
And of course... the name of the product; "hush"; kind of a clue.
My previous reply came out wrong. I re-read the article and a few comparisons on the web. Hushmat seems to also provide great cooling properties; but you have to admit they first developped the product for sound deadening. Cooling (by choosing the right material of their sound deadener) was just gravy for them. They were targetting sound.
I found that a lot of people tackle sound & heat with 2 products. The article that was pointed out was supposed to be about heat only, but they seemed (to me) to have mixed both type of products; which is why I called it unfair. Turns out my own critic was unfair. Apologies!
In one of his videos; he shows that it sticks to anything; even grease/oil covered surface. I`m sure you did your research, but regardless of what he says about how well it sticks, you should try to prep the surface as good as you can.
I`m curious as how far up you plan on installing hushmat into the firewall and the top front. Let us know how it goes.
Vette(s): 1981 Great White Shark. Red Interior, 350/190hp. PS, PB (SS), A/C CC, T-Tops, Going to remain as Stock as possible. Served three years in Active Duty Army, then Retired Air Force after 34 years! Badger State Vetts Car Club. 175,000 Original miles!!
Trust Me!! The 81 gets hot!! I have not put any heat shield on mine yet but I am reading all this info with interest!!
If you put hush mat in your car for cooling you will be pulling it out within a month - it sucks at that. I installed dyna pad for heat and it dropped my interior from an uncomfortable level to very comfortable - save your money buy what works pal!

DynaMat has precut corvette kits now. I put it in the 69. Easy to install and make s a difference. I like their products. We install alot of them in the Home electronics business, and have yet to be disappointed.
