1. Scribe separating point on A-pillar outer paneling (1) and cut (areas S and T).

   Take separation points from vehicle.

2. Grind mating surfaces down to bare metal on A-pillar outer paneling (1) in crosshatched areas.

   Do not coat bonding surfaces with zinc dust paint (area S₁ and S₂ ). Otherwise adhesion problems 2 can occur. Observe pretreatment of bonding surfaces.

   Grind spot weld flanges down to bare metal on both sides.
