I want to sound deaden my rear door (hatch) because it rattle's like a b*tch. But I don't know what to do with it exactly. I am looking at either Damplifier or Damplifier Pro. I will have about 10 sq feet to do. My quesitons are this: Which one should I go with (from above) and on either one, should I double layer it, or is a single layer adequate? I have never dealt with sound deadner before so I don't know how much to add. And, do I apply it to the metal side of the door frame, or the plastic cover side?
Thanks
