Dynamat Install
Hey all, has anyone out there dynamat-ed the floor of the C1?
My firewall insulation is deteriorated and I am curious if installing dynamat insulation in the firewall area is adequate in place of the firewall insulation.
Thanks

Dynamat is a noise supressor, mainly. And very much overpriced. We did an entire GTO with Frost King for under $40. About 80 to 100 times cheaper than Dynamat.....and it keeps out the heat as well as the noise. Still tomb-quiet 9 years later.

Has anyone had to replace the interior firewall insulation?

I agree, Dynamat is overpriced. I too did my 59 with Frost King and am very happy with it.

I used jute padding from a roll I had to replace all the crappy brown stuff that was falling down in my 64 from under the dash. Nice part of working with a roll is you can make your own pieces and work in small sections at a time. On a C-1, there is no insulation on the underside of the dash, just the firewall and it's molded pieces with a hard backing. If your original is not too bad, I'd leave it alone and just do the floors and doors.. They do make a nice reproduction, but it is a bit of work to install it since you have to take everything out to get the pieces in the way the factory did.

I believe this is it. I ordered a roll and should deliver today. Will let you know if it’s not the right stuff.https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1
