Dynamat the Doors

I've got a little project planned for the weekend, I plan to dynamat the doors. Depending on how this goes, I may add more later to other parts of the car. I've read several threads/post on this. I'm looking for a little confirmation before I get started.

To do the the doors, I need to remove the interior door panels and put a layer of dynamat on the inside of the outer door skin? Do I need to put any (is there any benefit) to putting any on the door door frame where the interior panels attach?

Any gotcha's I should be aware of?

 

I got sidetracked yesterday and only had time to do one door - the passenger side. Took about an hour to do from start to finish and I'm quite confident the other doors can be done in 30-40min each after getting the first one done. It does take 2 "sheets" per door. I found it easier to make paper patterns for above and below the door bar. I had the roller so I used it and it did make things a little easier but there's not a lot of room to get your arm and roller in there let alone roll. I don't think it was necessarily needed, but it was nice to have and it did smooth some of the places out especially the ends where the sharp metal edge was exposed.

All in all it was an easy job if you take your time and don't rush. There's enough room to work you just need to be patient when sliding the unbacked dynamat sections into the door frame. I'll grab some more sheets for the back doors (to make sure I leave my OCD in check) and I'll finish the doors next weekend or maybe after work one day.
