As for this, how many layers of the "cheap stuff" is needed to make the same difference one layer of higher end product ? the cost of Peel and seal times the amount of layers needed almost equals the price of the good stuff. Deadener does not stop rattles 100% , hence why expanding foam or additional bracing is needed in certain areas.
Also note though, most people misunderstand what Dynamat, Second Skin, Peel and Seal, etc is really for. All that stuff really does is add weight to panels and what not, to prevent them from vibrating more. More weight= less vibration. Yes, it will help with road noise slightly, but its not the best route to take if you wish to kill outside noises. Second Skin makes something thats called Luxury Liner, which is a layer of foam almost that you roll out in the car. I would recommend apply that to your floors and whatnot if you want to really "deaden" the car.
