Dynamat or Fatmat??

So I'm cutting and buffing my new paint and here comes my neighbor from across the street. Compliments my paint and I show him the difference between the fresh paint and the cut and buffed. Next thing you know we are talking about sound deadner and he says he will be right back. He brings over 2 and a half rolls of sound deadner that he had bought for his Honda Pilot. aparently Honda is pretty skimpy on sound deadending material to save weight to get those fuel economy ratings. He bought too much so he gave me the rest. SCORE!
