Couple of questions on sheetmetal/bodywork

I am tackling the sheet-metal work on my 68 dart project. I seem to be progressing OK, albeit a little slow. My intention is to hand all the prep work off to whoever I have paint the car so that the prep work is done the way they want. I have all AMD sheet-metal and so far it seems to go together quite well. I am working on the drivers quarter panel and hit a snag and I am not quite sure what to do. Overall the panel is fitting in nicely but the small details are causing me frustration. In the pictures below you can see the body lines are lining up nicely but at the top of the door the curve and body line don't seem to be as pronounced as those on the door. One picture kind of exaggerates it, but even though the tops are lined up, the fold is off by about 1/8 inch. I can't raise the panel, because the edges line up, and the other body lines are lined up. Do I have to get in there and start working the metal, or does this fall under the paint prep department and need to get worked in with some filler or something? It seems to me like it would be an awful lot of filler, and in a highly susceptible place.:burnout:
