Car is back from Paint !!!!

Beautiful car. I love the Notchbacks. Do yourself a big favor and Dynamat the inner roof skin. You can get bulk 0paacks at Amazon.com with free shipping. I would also do the firewall starting up as high towards the bottom of the windshield as you can get it, but just down to hour heels and maybe a few spots where your mufflers will be. Then put a few strips on the inner and outer inside door skins just to deaden the resonation.
Once you get that in, line the entire car's interior with "The Insulator" from Aircraft Spruce. It's very reasonably priced and when used with that aluminum tape with the wax paper peel-off liner. You can seal dozens of custom sized pieces together into one big blanket that keeps out road noise, odors and sound better than anything I have ever found.

My car is quieter than a Bentley, while I'm driving down the road. It sounds like you've walked inside an anechoic chamber or a bank vault when you sit in it. It's well worth the effort. and few hundred bucks to do it.

The trick is to use the palm of your hand and pound lightly on all the interior surfaces and only Dynamat the panels that resonate when tapped. The blanket of insulation is what really does all the sound deadening and keeps out fumes and makes the car mush more comfortable to drive. They do allow for a lot of noise through the wheel wells too, so cover those with Dynamat as well. I did have to glue the headliner blankets up, but the rest of the blanket can be pulled out and re-installed in one piece. I do tape all the edges down just out of sight of the edge of the trim, so you can't see it.

You can find rolls of "The insulator" by the foot in 2 foot wide and 4 foot wide rolls at the aircraft supply chain "Aircraft Sruce" here's the link. The aluminum duct tape is available at any hardware store.
It looks like they only have the 4 foot wide sections now, but ask if its available in 2 foot wide sections. I would get the double sided aluminum rather than the single sided, so it is easier to form, stays dry easier and make sure you plug up all your holes and use new seals on your doors etc.

I used single layers except for from where your feet rest on the floor to the rear where the back seat starts. I did not double up on the transmission tunnel. I went one inch thick there. When you pound your fist on my carpet, you can't even tell it's there.

Remember, Dynamat is not intended to cover the entire interior of your car. It is designed to stop the panels from resonating and having sound pass small amounts of heat pass through it. It's "The Insulator" blanket that does most of the work. I learned how to do this by copying how they insulate small high-end aircraft. The results are amazing!
