For 1990-2009 cars only
- Disconnect the battery feed rear window defogger system.
- Inspect the rear window defogger grid lines and mark the grid line breaks on the outside of the glass with a grease pencil.
- Clean the grid line area to be repaired. Buff with steel wool and wipe clean using a cloth dampened with alcohol. Buff and clean about 6 mm (1/4 in) beyond each side of the break in the guide line.
- Install the grid line repair decal or 2 strips of tape positioned above and below the repair area.
- At room temperature, apply the grid line repair material to the repair area using the applicator provided with the kit.
- Carefully remove the decal or tape.
- Apply heat to the repair area for 1-2 minutes holding the heat gun nozzle 25-50 mm (1-2 in) from the surface (Distance A). A minimum temperature of 149°C (300°F) is required.
- Inspect the grid line repair area. If the repair appears discolored, apply a coating of tincture of iodine to the repair area using a pipe cleaner or fine brush. Allow iodine to dry for about 30 seconds and carefully wipe off the excess with a lint-free cloth.
- Test the rear defogger operation to verify the grid line repair.
Important: Repair decal or tape must be used to control the width of the repair area. If a decal is used, be sure the die-cut metering slot is the same width as the grid line.
Notice: The grid line repair material must be cured with heat. To avoid heat damage to interior trim, protect the trim near the repair area where heat is to be applied.
Important: At least 24 hours are required for complete curing of the repair materials. The unit should not be physically disturbed until after that time.
