I recently repaired my own delaminated door panel on driver side of my '02 SLK320. First, there are a few screws to remove in your door panel. There are a couple in the chrome end door trim, one in the door latch trim and one behind the handle trim itself. Once these are removed the door panel snaps off fairly easily. I then took the panel to a flat surface and finished removing the delaminating part. You can see where the factory adhesive was applied. By following their pattern, I applied a generous portion of heavy duty gorilla glue to the area where the two seperated pieces go together. I then strategically placed weights to help press the two pieces together. Once the glue dries, reinstall the door panel in reverse order. The gorilla glue holds like wow! The door has that "new" feel again.
