In order to repair the leak, apply 3M Flexiclear(TM) clear body sealer, or equivalent, to the joint. Apply the sealer into cracks or voids as much as
possible beside and under the molding for at least 38 mm (1-1/2 in) rearward. Make sure that the front edge is completely sealed. This operation
can be done without removing the molding (Figure 7).

touch-up paint.
