I removed the one on the drivers side today. Not too difficult, but I do have some good tools to pull with. Think ice pick that is bent 90 degrees, some with hocked ends and some just a straight 90. I also used a piece of vinyl to shield the paint of the roof from the tools. Once it is started from the rear it comes out of it's grove in the rubber seal. It is shaped like a "T" with the vertical leg squeezed down into a grove in the rubber. The rubber is glued to the car. The trim piece is fairly rigid, so working carefully I was able to remove it without bending or twisting. Simple lift it out of it's grove starting at the rear.
It is sanded and prepped; tomorrow I'll purchase/order Dupli-Color self etching primer and cover coat with Mopar Graphite Metallic both in spray cans. A little silicone grease and it should slip right in again; Better than new.
