2. Using an O-ring pick or similar tool, pull the molding away from the A-pillar. Apply 3M Super Silicone Sealant (see REQUIRED MATERIALS) under the rubber molding along the full length of the A-pillar

3. Press the molding against the A-pillar with your fingers to smooth it out and make sure it sits flush.

5. Repeat steps 2 thru 4 on the other A-pillar.
