What Drdave posted in right on the money... usually there is light coverage if any coverage of paint on the metal roof under a factory top, and the 1/4 panel seams are very crudly finished... on original vinyl top cars, its not uncommon for this area to look and feel very wavy/rough, as the original cloth-backed vinyl didn't hide too much. Assembly line workers didn't spent too much time doing any finishing work in the roof area knowing the car was going to get a vinyl top.
