My picture isnt that good but just to make sure I am clear....there are two sections I am showing in the pics. one is the lower part that is definately vinyl skinned this part has the ashtray in it and is the entire lower rectangular part shown in the pics. You can buy the vinyl cover for larger rectangular piece and even the larger metal piece that the vinyl glues to. This vinyl has a small bit of padding behind it.
Tha part that I am trying to fix is that upper arcing part (comes up from armrest base and arcs a bit backward). this screws to the actual vinyl armrest rectangular section. this arcing piece is metal and has a very thin coating (I think it is paint) that is textured. This is the coating that is flaking off on my piece. I might have been mistaken in calling it a vinyl skin but that is what I thought I read.
I'll try to find that catalog that lists them. they dont carry them as repros only as a "used" part.
