My project is getting close enough to interior that I want to start exploring options. I have looked on the web and have found many varying reviews of all the different sound deadener products. I found this site www.sounddeadenershowdown.com/ with lots of good info. But it also look like you can get carried away with it. That site shows some great products and techniques, but man, that's a lot more than I was looking to get into. I really do like the roof treatment he did www.sounddeadenershowdown.com/how-to/roof He does not use a traditional stick on product like Dynamat, he uses Closed cell foam and Mass loaded vinyl which is a lot like the sound deadening used in new cars today. So it seems to me there is some real science at work here vs just covering the entire inside of your car with sticky pads.

The science behind the sticky pads is sound, too. Pardon the pun. The only thing you have to be careful with is that most sound insulation material can trap moisture and lead to premature rusting. To me, that was always the biggest virtue of the single pads of foam insulation.
I'm still trying to decide what I want to do with my car; when the paint shop finishes it... and I hope to be able to add more information on the subject.
Though, one thing I've already learned is that, if you plan to use rubber flooring, as I do, then you had better take precautions against condensation beneath the rubber. My solution is going to be using whatever form of insulation I choose in the center of all the floor pans and to keep a channel of air that can flow and circulate to prevent moisture buildup from rusting out my floorboards.
