- Clean the weatherstrips and the contact surfaces using solvent.
Important: Ensure that the surrounding areas are free of chalk or powder.
- Apply powder or chalk in an unbroken line to the contact surface of
the weatherstrip around the perimeter of the following areas:
- Close the panel completely without slamming. This presses the
weatherstrip firmly against the mating surface.
- Inspect the area of suspected windnoise:
| • | The chalk or the powder line will be marred where
contact is good. A corresponding imprint will be on the mating surfaces. |
| • | Gaps or irregularities in the powder or chalk line on the mating
surfaces indicate areas with a poor seal. |
