DYNAMAT installation help
Not the Dynamat brand, but "The Insulator" brand, a foil backed heat barrier/sound deadener/insulation that is aprox. 5/16" thick foil on one side and insulation on the other side.
I'm planning to apply to my 67 Nova's floor boards, behind back seat, inside doors, and even above the headliner to reduce the "tin can" effect and a little resonance from the exhaust through the metal floor pans.
Any tips or opinions on installing?
Glue down? Foil down or insulation down?
Affect on carpet fit?
To roof above headliner?
Get wet inside door? Smell if wet?

Just my opinion...foil is to reflect the heat/etc away from the interior. You would want it face down or outwards as a barrier. I would glue it down, but maybe let the carpet float on top of it. The carpet being held in place by normal trim pieces with screws. Maybe some contact cement on verticle area's (trans tunnel, etc...)

Under (above, actually) headliner installation:
I used 3-M yellow spray contact cement to adhere this type of insulation to the metal roof of my '67 GTO. Wait until both surfaces are barely tacky and then apply using a hard roller to complete the bond.

The foil goes up. There is no issue with carpet fit. It is a lobor intensive job. I did not put it inside the door but that is a good idea. Also on the inside of the roof. I felt it was a nice addition.

Hi Jeff:
Here is what did with my coupe. This product is similar to dynamat, but slightly thicker. Cut to size, Peal off and stick. My Advice is to do it on a hot day! Makes it much more manageable.
