The following operation steps are shown on the left component for model 221 and must be performed analogously on the right side in the event of damage.

Grind connection surfaces on inner rear wheelhouse (1) down to bare metal in cross-hatched areas with round wire brush.
Grind spot weld flanges down to bare metal on both sides.
Using zinc dust paint, coat insides of spot weld flanges and riveted joints that were not additionally bonded.
Do not coat bonding surfaces with zinc dust paint to prevent adhesion problems (areas A, B, C, D, E and F).

Observe pretreatment of bonding surfaces.
