Abstract: A trim system includes aesthetic trim components adapted for interconnected attachment to painted exterior vehicle body panels. The first and second trim components have edge flanges that define a joint line between their outer surfaces but that overlap to prevent see-through between the trim components. The first and second trim components include a recess and a hook frictionally engaging the recess to retain the first and second trim components closely together to minimize a width of the joint line. The first and second trim components also include an alignment flange portion and a clamping flange engaging the alignment flange portion to maintain an optimal flushness of the outer surfaces. At least one of the edge flanges has a reduced thickness to minimize a thickness of the assembly, with the hook and clamping flanges also being designed to minimize total thickness.
