I recently purchased a 1955 Mark VII M and I've removed all of the trim and moveable panels - the fender skirts, front bumper valance, and sunroof (could not get the cowl vent cover off due to extremely rusted-in screws), and it is now in for a new paint job. The sunroof was extremely difficult to slide open and closed and so before I put it back in after painting I'm wondering if anyone has some advice on what to do with the tracks or the sunroof itself to help it slide more easily.
