When new, does the white vinyl attach a) "over" the window around the perimeter or b) edge to edge, if you see what I mean? Recently been helping a neighbour fix a (black) soft top. where the glass rear window was detaching from the soft top at the top of the window. On that one, the edge of the soft top around the window attached to just the side edge of the window. Couldn't replicate that at the top of the window without removing the headlining inside the car. So just stuck the detatching soft top edge on top of the window around the perimeter. Used clear Bostik contact adhesive (extra strong). Working fine so far.
