4. Using isopropyl alcohol and a clean cloth, wipe the windshield glass where the rain sensor and rain sensor bracket were mounted to remove any residual adhesive, contaminants, or loose glue particles.

5. Wipe glass with a clean cloth to make sure the glass is clean and dry.

6. Apply specified primer onto a clean cloth.

7. Insert a cotton swab or equivalent, onto the wet area of the cloth.

8. NOTICE: Do not apply primer to the rain sensor view window area.

Using a cotton swab or equivalent, apply the primer onto the contact area of the rain sensor bracket area of the windshield glass.
