The reveal moldings for the windshield, quarter windows, and the rear door are a vinyl trim which fits between the edge of the window and the body. The reveal moldings are hand-pressed into place and retained with urethane adhesive. The windows do not need to be removed in order to replace the reveal moldings. Certain reveal molding applications may require you to trim the reveal moldings. In order to allow room for both the molding and the urethane adhesive to fit in the cavity between the window and the body, trim the reveal molding as needed.
