No mystery. There was no paint applied to boxed areas, or even hard to reach unboxed areas. So as seen in the pic, the rust comes from inside and you wind up with a painted surface that has almost nothing but rust behind it.

In the mid to late 70's they started using more galvanized metal, and dipping the bodies in primer. This improved things a lot.
