Nice job there. Dynamatted mine couple years ago, made a tremendous difference (and a huge fan out of me). Doors thunk shut, firewall noise reduced, overall more 'solid' feeling.
The roof...
Mine was originally just stuck to the roof, then headliner reinstalled. Worked great... until it was about 95 in Alabama heat and the thing drooped mightily. Plan B.
Adhered the Dynamat to some foam-core, then the headliner to that. A very good look, but NOT as smooth as the Coraplast. Wish I'd seen this first!
The thing is, make sure your headliner is totally clean of the awful foam dust before attempting to stick it to anything.
Great job!
