5. Buff the grid lines that are to be repaired with steel
wool. Wipe the lines clean using a cloth dampened
with alcohol. Buff and clean about 6 mm (0.25 inch)
beyond each side of the break in the grid line.
6. Attach a grid line repair decal or two strips of tape
above and below the repair areas.
S A repair decal or tape must be used in order to
control the width of the repair areas.
S If a decal is used, the die–cut metered slot must
be the same width as the grid line.
7. Apply the grid repair material to the repair area us-
ing a small wooden stick or a spatula. The grid re-
pair material should be at room temperature.
8. Carefully remove the decal or the tape.
Notice : The grid line repair material must be cured with
heat. In order to avoid heat damage to the interior trim, pro-
tect the trim near the repair area where heat will be ap-
plied.
9. Heat the repair area for 1 to 2 minutes.
10. Hold the heat gun nozzle 25 mm (1 inch) from the
surface. A minimum temperature of 149°C (300°F)
is required.
11. Inspect the grid line repair area. If the repair ap-
pears discolored, apply a coating of tincture of io-
dine to the area using a pipe cleaner or a line
brush. Allow the iodine to dry for about 30 seconds.
Carefully wipe off the excess iodine with a lint–free
cloth.
12. Test the operation of the rear window defogger in
order to verify that the repair was successful.
Important : At least 24 hours is required for complete cur-
ing of the repair materials. The repair area should not be
physically disturbed until after that time.
