This first issue was a weird one: it looks as though the the factory let this Charger leave with voids/gaps in the joint between the top of the right forward pillar and the roof skin. The vinyl top didn't help things any and the top forward corner of the windshield channel rusted through in several places. It was the only spot around the front window. Before and after pics showing the patches...
The right rear pillar was puffing out at the bottom of the quarter to roof joint/seam. The bottom of the lead joint was melted out to see what was needed. The rusty area was cut out and replaced with a fabricated patch. Before and after picture...
