Hi All,
Got a question for those who have dynamatted their doors. Did you cover the large "access" hole on the doors for the power window rails?

 

Cover everything (except the holes the door skin sticks into)! Even deaden inside of the doors.

 

Skip the dynamat on the interior sheet metal. It doesnt need damping, nor do you need the sticky mess or the pain of replacing it whenever you work on something inside the door. Use foam and/or mass loaded vinyl/lead while still covering the outer sheet metal with damping mat. You can just velcro it on and you will get MUCH better results.
