Any one ever used Dynamat prior to putting up a new Headliner ?? If so any Pro's or Cons ???

 

Well I just got done doing it with fat mat I don't know the pros or cons yet.
But just to name a few that I have at the moment
I got the old tar paper out asphalt based
I cleaned the rusting bare metal and etch primer in before installing

Looks Good, I just finished scrapping all that mess off. I sprayed some Ospho after getting as much off as I could... I also sprayed primer and paint... I was just worried about the Dynamat one day coming loose with the Florida Heat and falling down.. However, from some of the comments about the Dynamat it seems pretty slim ...
Thanks

 

I also installed insulation using the 3 m pray glue

I figured, if it does fall at a later point the headliner rods should hold it in place.

 

My original insulation was well intact so I left it. Didn't want to chance having something new come down. Especially since installing a headliner is such a treat ;-)
