Dynamat
I used a product called Thermo Tec. It was half the price of Dynamat. It was $40 per box of 60" by 36". I used four boxes. It is peel and stick. I did the entire floor, front and back, the roof and pillars as well as the inside of the doors. My car is nice and quiet now. Jerry

Any issues with foil type products not allowing air/breathing of fiberglass? Possible damage down the road? Especially on inner door skins and roof where paint has sealed the outside and now we are sealing the unfinished inside?

I've read that the asphalt-based products should not be applied to the insides of the doors or roof, for fear that oils will bleed into and through the fiberglass and affect the paint. I don't know that anyone has presented proof that this happens, but I would heed this advice if it were me. I insulated my 67 ragtop with B-Quiet but avoided applying it to the door insides.

Don't Use Dynamat
Go to Elemental Designs website. I have used their stuff in three cars. Better than Dynamat and cheaper. More flexible too. I've used their 45 mil product and it works real well.

For what it's worth, I did the whole interior of my coupe, including the roof under the headliner and the insides of the doors with Dynamat. It took about 2-1/2 boxes. I got the dynamat on e-Bay for around $100 per box, probably has gone up since.

I did my 66 roadster with a box and a half... There were 9 sheets in a box... I have 4 1/2 sheets left over... I fixing to put it for sale for 30.00... Dynamat was one of the best things I did to the car.. It took out the road noise and the car just feels better when driving without that road noise. Now I can really appreciate those side pipes!

Kool Mat
Has anyone used a product called Kool Mat? I have not seen any posts on this product, I guess because of its costs. When in Carlisle I stopped at vendor who said he sells lots of this to Corvette guys. Any feed back to find out if it is worth the extra cost?
Thanks
Bob

I agree that such is the way that it should be. However, I've had the experience that many have had of a factory A/C compressor leaking oil, which gets onto the underside of the hood and ruins the paint on the shiny side of the hood. Asphalt is just very thick oil, so I presume that the lighter fractions in it might bleed through the fiberglass over time (years?) and harm the paint. IMHO.
