Check out Sound Deadener Showdown if it's still around. His theory, supported by testing, is you only need a small percentage of the stick on butyl to take the bong out of the sheet metal. Then a layer of isolating foam, then a layer of rubber.

Must be something to it since the manufacturers like Dynomat are selling the other materials.
