NOTE:
- Any breaks longer than 25 mm (1 inch) in one grid cannot be repaired. The back window glass must be replaced. Breaks equal to or shorter than 25 mm (1 inch) the heated back window grid wire can be successfully repaired by using the following procedure.
- Obtain a repair kit.
- The vehicle should be allowed to reach 16°C (60°F) or above.
- Clean the repair area with denatured alcohol.
- Place the grid line mask over the break aligning the cut-out slots on either side of the repair area.
- Apply the epoxy to the repair area.
- Remove the mask without disturbing the epoxy.
- Use the special tool to heat the repair area for 1 to 2 minutes at a distance of about 25-50 mm (1-2 inches). This procedure should heat the repair area to approximately 149°C (300°F).
- The heated back window may be energized immediately after the repair. Optimum hardness and adhesion will occur after 24 hours. Do not disturb the repair area until that time.
