All I can offer is my own experience(s) with Dynamat-I think if you put it on an outside panel you will see some deadening,but not the full effect-the reason I feel this way is that there is a very noticeable difference in the "tone" of the Door after I put it on (it "dulls" the metal sound to a thud)-

I would put it on the outer skin if at all possible (but on some cars the window mechanism does get in the way)-
