I am planning on doing a whole lot of sound deadening in my '05 over the coming months. After doing some research and reading past threads I have decided to go with RAAMmat. My goal is to quiet the interior as much as I can. I have a long highway commute to work every day, and coming from a higher end sedan I miss the quiet comfort and solid feel.
By "a whole lot of sound deadening" I mean really going all out. Floors, door, roof, trunk, firewall, etc.
I'm looking for anyone who has installed RAAMmat and had it in their car for a few years. How has it held up? Is it still stuck in all of the places you put it? Has the closed cell foam deteriorated at all?
