Filament Repair

WARNING: This page is about a different car, the 2008 Mazda 3. However, it is still accessible from the selected car via links, so may be relevant.

Clean the filament using isopropyl alcohol.
Attach tape to both sides of the filament.
Using a small brush or marking pen, apply silver paint.
After 2-3 min , carefully remove the tape without damaging the applied area.
CAUTION:
- Do not operate the rear window defroster until the paint is completely dry. It may cause other malfunctions if it is used before the paint is dry.
