Installed sound deadener on the roof and floors. I put 2 layers of radiant barrier on the passenger floorboard to go to combat with the heat from the Cats. The doors will come later, I should have enough material left over. Check out my Bling!
How has this held up and did it do as you intended to cut down on noise and heat? I'm think of doing this on my DD to quiet it down. Did you purchase the radiant barrier from Home Depot or Lowes, etc. ?
