- Measure and cut a new weather strip to length.
- Apply the new weather strip, ensuring a tight seal.

Step 3: Check Sunroof Alignment

Open the Sunroof:

- Apply the sealant along the frame of the sunroof and allow it to cure as per the product instructions.

Step 5: Final Testing

Water Test Again:
- Using the garden hose, pour water over the sunroof once again to check if the leak persists.
- Ensure that all drainage is functioning correctly.
Reassemble Any Removed Components:
