Installation Procedure

    Important: Loose urethane and/or a rough surface on remaining urethane may cause sealing problems during installation.

  1. Clean old sealer from body pinch weld area using a razor knife. Leave a thin film - approximately 1-2 mm (0.04-0.08 in) around the perimeter of the window opening and windshield (if being reused).
  2. Clean entire window opening and glass bonding surfaces with a clean lint-free, alcohol dampened cloth.
  3. Notice: To prevent corrosion, paint damage around the window opening by the power glass removal tool must be covered with pinchweld primer. Do not prime over existing urethane. Follow manufacturers recommendations for drying time.

    Important: Shake glass prep primer (Clear #1) well before applying.

  4. For new windshield only - Apply glass prep primer (Clear #1) around the entire perimeter of glass using dauber. Wipe dry with a clean lint-free cloth.
