Just a suggestion, and not many people follow it anymore; but don't just use filler on your C pillar joints. Find someone who still can do lead. The quarter panel joints need too much filler, and when filler gets too thick, it WILL crack. Not today, maybe not tomorrow, but eventually it will. And there goes your nice expensive paint job. Newer cars don't have as big of a joint to fill, and can get away with it. I know people do it all the time, but I wouldn't. JMO.
