<VV> Sound deadening --- was mufflers

[Spencer Shepard]

Dynamat is effective and there are other, cheaper, alternatives. I seems 
that the most effective place for it would be under the headliner. I believe 
the old Solar Cavalier put something there. Of course it may not be worth 
the effort unless one was replacing the headliner anyway. Anyone have 
experience with sound deadening material on the roof? If so, what glue glue 
works?
