Spot on and sound advice
Jake, please do some reading before spending a load of money on products and falling into the trap of putting a dynamat type product all over your panels - it is simply not needed.
What you have to think of is that there are different types of sound that you need to work against and for that reason you need different products. In the most basic form - some Sound Dampener (e.g. dynamat) and some Sound Blocker (e.g. a closed cell foam product such as Silent Coat).
Put simply, a metal panel is subject to vibrations that case soundwaves to resonate through the panel and into the car at low frequencies - all you need to do is apply 'dampener' to about 50% of that panel in the centre and that will be enough weight to stop the vibration. There is no need at all to apply dampener to every inch of every panel. All you'd be doing is adding weight without increasing the sound dampening abilities above and beyond what half of the material could do. Once you've stopped that sort of sound, whatever material you're going to use as a 'blocker' needs to be applied on top; this should cover the whole of the panel in question. I have used these principles to great effect on my own Supra but unfortunately didn't take any pics before the interior went back in
