Cabin Sound Deadening

when I replace the headliner, I should put sound deadener and insulation up there.

Has anyone here done that with modern materials?

I installed Hushmat in the roof of my 69 Charger.

Did it make much of a difference?

I just did the Kilmat stuff in my 65 based on the feedback in this thread. Great stuff for the price!
