Anti-corrosion<br />
treatment<br />
The entire car undergoes a series of anticorrosion<br />
processes during production.<br />
These include electrophoretic priming,<br />
PVC-based coating to protect against stone<br />
chip damage and corrosion, and treatment<br />
of body cavities and members with thin,<br />
penetrating rustproofing oil.<br />
In addition, most body panels, such as the<br />
bonnet, doors and floor pan are galvanised.<br />
The anti-corrosion treatment on some parts<br />
of the car is constantly exposed to wear and<br />
prone to damage. This applies particularly<br />
to the underside of the car and inside the<br />
wheel arches, where grit, road salt and the<br />
like that are thrown up can give rise to corrosion<br />
where the underseal has worn away.<br />
The extent of this obviously depends on the<br />
conditions in which the car is used.<br />
Accordingly, make it a habit to hose the<br />
underside of the car often and to inspect<br />
the condition of the underseal. The anticorrosion<br />
warranty does not relieve the<br />
car owner of the need to carry out normal<br />
maintenance to the rustproofing and to<br />
make good any damage.<br />
Use a hose to clean the underside of the car<br />
thoroughly. After it has dried, use a brush or<br />
spray to apply a viscous anti-corrosion<br />
agent to any worn or damaged areas, to prevent<br />
the onset of corrosion.<br />
Even after the anti-corrosion warranty has<br />
expired, it makes good sense to continue to<br />
maintain the rustproofing.<br />
Seams in the body, especially those in the<br />
doors and boot lid, are particularly vulnerable<br />
to corrosion from the outside, caused<br />
by grit and salt thrown up from the road, and<br />
to corrosion from the inside, largely as a<br />
result of condensation. Keep the seams<br />
clean and at the first sign of any rust, apply<br />
a thin anti-corrosion agent using a spray can<br />
or a brush. We recommend that you contact<br />
an authorised <strong>Cadillac</strong> workshop.<br />
