Using a small brush or marking pen, repair the filament with silver paint or equivalent.
After 2-3 minutes , carefully remove the tape without disturbing the repaired area.

CAUTION:

Do not use the rear window defroster until the paint is completely dry. It may cause other malfunctions if it is used before the paint is dry.

Use a hot air blower heated to 150 °C {302 °F} for 30 minutes or let the paint set for 24 hours at 25 °C {77 °F} to allow it to dry completely.
