Grid Wire Repair

NOTE: A single break or any breaks that total 25 mm (1 inch) in one grid cannot be repaired, and the back window glass must be replaced. Use the following procedure for breaks less than 25 mm (1 inch) long.

Breaks in the heated back window grid wires can be successfully repaired by using the following procedure:

The service kit consists of five individual kits which include the following pieces:
^ One epoxy adhesive hi-pack
^ One application stick
^ One grid line mask
^ One set of instructions

Surface Preparation
1. The vehicle should be brought inside and permitted to reach 16°C (60°F) or above.
2. Clean the repair area with denatured alcohol.
3. Ensure that the repair material is not beyond the expiration date. If the hardener has crystallized, immerse the packet in hot water until the hardener liquefies.







4. Place the grid line mask over the break in the grid line, aligning the cut out slots on either side of the repair area.
5. Prepare the epoxy bi-pack:
a. Remove the separation clamp.
b. Thoroughly mix the resin and hardener together by kneading.
c. Cut a corner off of the epoxy bi-pack.







6. Apply the epoxy to the repair area using the application stick.
7. Carefully remove the mask without disturbing the epoxy.







8. Use Rotunda Heat Gun 107-R0300 or equivalent 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).

Curing
The heated back window may be energized immediately after the repair. Optimum hardness and adhesion will occur after 24 hours, and care should be taken not to disturb the repaired area until that time.
