When putting sound deadening on the doors do you remove the clear plastic and put it straight on the metal or does it go over the clear plastic stuff?
sound deadening ?

I have seen only one installation where the vapor barrier was left in place and the dampening material applied on top of the vapor barrier. The dynamat website has some decent installation instructions and lots of pictures. Dynamat instructs users to remove the vapor barrier. In theory, the dampening material will be the vapor barrier.
I'm in the middle of installing dampening material (and closed cell foam in my 62 (floors and doors). I removed the vapor barriers. The vapor barriers have to come off to apply the dampening material to the inner door skin. When you apply the dampending material to the innner part of the door (the part behind the door panel), the key is lots of patience. You will make cut outs for door hardware, speaker, etc., but still close off the door. Otherwise, you will not have an effective vapor barrier. The doors have been the most time consuming part of my project.

I carefully removed the oem vapor barier, installed sound deadening over complete door with only necessary slits & cutouts, then reinstalled oem vapor barrier on top.
Sound dampening won't "dampen" the metal if it's not stuck directly to it.

Trying to understand the description... so the dampening material goes on in the exact same location as the vapor barrier originally was? (inner doorskin?) Or does it go on the inside of the outer doorskin?

I actually left the vapor barrier in place when I did my front doors. No clearance issues for the panel. I cut the strips to fit, held up to make the holes for the various protrusion, flipped it upside down and cut the other side.
No issues, I only had my truck about a month and could still notice a considerable difference in sound with minimal windshield time.
