It helped, but the car is still noisy.

now I'm ordering materials to coat the inside of the doors. I will see if that helps.

the guys that make GT Mat are offering free samples (10 ft square) of there product to members. you will need more like 30 to really get after the hatch and (I'm guessing) 20 or so for the doors (some is wasted when you trim the sheets to fit your panel shapes.)

Here is a photo of my Hatch as i was just getting started putting down the mat. I spoke with my dealer service manager and he tols me how to get all the trim out. (it is easy)
