Important: 

  • Ensure that the grid line repair material is not beyond the expiration date.
  • Repair decal or tape must be used in order to control the width of the repair area.
  • If the repair decal is used, verify that the die-cut metering slot is the same width as the grid line.
  • Thoroughly stir the grid line repair material until a uniform color appears.
  • Verify that there are no air bubbles in the grid line repair material in the repair area.

  1. Use a grease pencil in order to mark the grid line break (2) on the outside of the rear window with a grease pencil.

  2. Using GM P/N 12346001 (Canadian P/N 10951643) or equivalent to repair the grid lines. Apply the grid line repair (2) decal or 2 strips of the tape above and below the repair area.
  3. Use the brush (3) in order to spread the grid line repair material (1). Ensure that the repair material covers all of the areas of the cut out.
    NOTE: The grid line repair material must be cured with heat. To avoid heat damage to the interior trim, protect the trim near the repair area where heat is to be applied.

    Important:  Use J 25070  capable of 260°C (500°F) or equivalent. If you do not use a heat gun, allow at least 24 hours at an ambient temperature of 21-32°C (70-90°F) for complete curing of the repair materials. Do NOT physically disturb the repair area until after that time.

    The grid line will be electrically operative immediately after the repair.

  6. Use a heat gun in order to repair the grid line:
    • Hold the heat gun nozzle 25 mm (1 in) from the surface.
    • Heat the repair area for 2-3 minutes.
