246 Car care and technical information
Two-coat enamel
As the name implies, two-coat enamel is
applied in two operations. The first coat, the
base color, contains the pigment, metal
flakes and binder. The second coat consists
of a clear enamel, which provides the final
gloss for the paintwork and protects the
base from moisture and environmental con-
taminants.
Touch-up stone-chip damage as follows:
1 Thoroughly clean the damaged area.
2 Apply the primer, base color and finally,
the enamel. To achieve the best finish,
apply two or three coats of primer.
Anti-corrosion
treatment
The entire car is corrosion-protected at the
factory in different stages by an electrolytic
immersion coating and a polyester-based
protective coating to protect against corro-
sion caused by stones flung up by the
wheels. A thin penetrating anti-rust oil is
also applied in cavities and body members.
In addition to conventional anti-corrosion
treatment like painting, underbody treat-
ment and cavity treatment, most of the body
panel surfaces are galvanized. These
include the hood, the doors and the under-
body.
The anti-corrosion treatment on the under-
side of the car and inside the wheel arches
is particularly exposed to constant wear and
possible damage, the degree of which will
obviously depend on driving conditions.
