Oh wow, you went whole hog on the deadener. I've been thinking about adding some of the butyl strips to my car to kill the resonance now that it's a primary driver and seeing a lot more road time. I have some foil backed jute type insulation under my carpet now, but that's it. Thought about doing the Dynamat type strips on some of the larger "flat" sections to see if it helps with noise any. The roof would probably be a better place for me to start though. I believe right now I just have the factory fiber type batting up there, so really very little noise or insulation control.
