Installation Instructions
Remove old weatherstrip and make sure to clean metal rails of any left over pieces of old weatherstrip. Install new weatherstrip corners first then work toward the ends and middle. Raise the top to rest on windshield but do not latch. Position the weatherstrip to set properly against windshield post weatherstrip and rear rail weatherstrip. After weatherstrip is properly positioned use adhesive to glue the weatherstrip into the rails, glueing only one section at a time in order to retain proper positioning.
