For 1990-2009 cars

1. Clean the weather-strips with solvent.
2. Clean the contact surfaces with solvent.
3. Apply powder or chalk in an unbroken line to the contact surface of the weather-strip around the perimeter of the following surfaces:

• | The rear compartment lid

• | The door

• | The door window

• | The hood

4. Ensure that the surrounding areas are free of chalk or powder.

Important: Do not slam the panel.

5. Close the panel completely.
6. Inspect the applied line on the weather-strip.

The weather-strip will be marred where contact is good. A corresponding imprint will be on the mating surfaces.

7. Gaps or irregularities in the powder or chalk line indicate a poor seal.
