Accessing inner door panel for Dynamat

Pat C.

Tree, I have the interior panel off of both doors, that was super easy to do. Had bought some nice tools to help. However, what I'm wanting to gain access to is, the inner skin of the exterior sheet metal(if door glass were down, you'd be looking at the sheet metal "behind" the glass. Don't think you'll gain much with just applying Dynamat to the first layer below the interior trim panel. I'm wanting to be able to tap on the outside metal and hear the dull thud of having deadened that part of our cars.
I have the time to run this down. Wish I had some sort of hand held camera, I'd video and show everyone how I think we should be attacking this noise problem correctly!!
Let me know if you have any other info. Think I'll post a new question under the chat section....Guess I'm looking at having to remove the actual glass???
