Grid Filament Repair
NOTE:
Any single or combination of breaks totaling more than 1" (25 mm) in length cannot be repaired. If first layer of grid (Brown) is damaged or missing, apply Brown touch-up paint (AL81-5477-B) before making repairs.
- Ensure vehicle is at room temperature. Ensure repair area is free of all dirt, wax, grease, oil, or other foreign matter.
- Mark location of break on outside of window. Using cellulose tape, mask area directly above and below break. See Fig 1. Break should be at center of mask and gap between tapes must not be wider than width of grid.
- Apply Rear Window Defroster Repair (D8AZ-19562-AA) in several smooth continuous strokes, allowing 3-5 minutes drying time between coats. Extend coating at least 1/4" (6 mm) beyond both sides of break. Allow 5 minutes to dry, then remove mask.
- Inspect outside appearance of repair. If repair compound is visible above or below grid line, remove excess compound. To do so, place single-edge razor blade parallel to grid and scrape gently toward grid.
