Solution

1. Preparation

Gather necessary tools and materials.
Ensure the vehicle is parked in a well-ventilated area.
Disconnect the battery to prevent electrical issues during repairs.

2. Remove Affected Trim

Carefully pry off the window trim using a trim removal tool.
Take care not to damage the trim clips or surrounding paint.
Store the trim in a safe place to prevent scratches or bending.

3. Treat Rust Areas

Use a wire brush or sandpaper to remove rust from the affected areas until you reach clean metal.
Clean the area with a degreaser to remove any dust and debris.
Apply a rust-inhibiting primer to the cleaned area. Allow it to dry according to the manufacturer's instructions.

4. Paint and Seal

Once the primer has dried, apply touch-up paint that matches the car’s color. Use multiple thin layers for an even finish.
Allow the paint to cure fully.
Reapply a high-quality sealant around the window edges to prevent future rust formation.

5. Reinstall Trim

Once the paint is dry, carefully reattach the window trim, ensuring all clips are properly seated.
Check alignment and gaps for a snug fit.
