Although I removed the original panels from the car years ago, I saved them for the purpose of saving the medallion and the ss strip. Getting them off the original panels last week was a real chore as the original adhesive (gray in color) was still holding like crazy. The ss strip was glued on also and had no pins. I ended up tearing the panel apart to get both pieces off.
The 3M weatherstrip adhesive sounds like a good idea. I have both the black and yellow.
