Thanks for the info. I will be doing some reading now but I have begun the work
Well I went ahead and installed the Lowes window seal stuff. I'm going to put it on the doors, quarter window area behind the panels, kick panels, and over rear axle area. I'm going to install the bubble wrap with the foil on both sides over everywhere I installed the window seal stuff with 3M adhesive. I think then the heat factor will be better.
I thought about doing that back in the 90's with Dynamat but I didn't want to add weight to the car and even worse, I was afraid it would trap moisture against the floor and rot it out. Also, I just love a loud car as long as it sounds good.
