I spent more time today on the dent and I'm calling it quits.
I masked off the dent area and applied some spray can paint stripper to clean the area and get rid of some of the damaged clear coat so I could see the surface better.
It's not perfect, and this picture might make it look better than it does up close and personal. But at the same time it's closer to the level of inspection that one might experience in a casual viewing.
I think I could do better with access to the inside of the skin with a roller or a body hammer and dolly, but that would be such a PITA.
I'm going to move on to the smaller and easier dents next weekend.
