I ran into an issue trying to repair some dents on the passenger rear door of my S213 wagon. My PDR guy wasn't able to access the dents from behind while going in through the window space and said there was some type of structural panel in the way. I pulled the door card and there was a metal panel bolted on and covering the access to the exterior door skin. I don't believe this panel was the issue but I opted not to remove it until researching further.

Has anyone opened up one of these doors to service the window actuator, etc and can confirm what if anything would be blocking the dented area in the pic below? If there is something removable after unbolting the interior panel, I'll dig in and see if I can get access to the door skin from behind.
