Most of the time what you will get is where your panel bond meets the filler you will eventually see a perfect line. This happens when you bake a car in a booth after priming or painting. It can also happen in the sun. I don't suggest panel bond on any seams that meet filler. Even though they say it's ok at a factory seem I have ALWAYS welded c pillars. The panel's should be flanged in my opinion. The way he put the panel on the style line created a lot of extra work for you.
