Preventing Corrosion

The vehicles of General Motors are
designed to have corrosion-resistant
properties. Most parts are designed
with special materials and protective
paint to help maintain a good
appearance, strength and reliability.
Although some parts in the engine
compartment and underneath the
vehicle may become rusty on surface,
the reliability or functionality of these
parts will not be affected.
Metal sheet damage
If the vehicle body needs to be repaired
or replaced, make sure that the
workshop uses proper anticorrosive
materials to restore the corrosion-
resistance properties.
Sediment of foreign substances
The following substances can damage
the paint surface:
Calcium chloride and other salts.
—
— De-icers.
Bitumen and asphalt.
—
Tree sap.
—
— Bird excrement.
Industrial dust.
—
Wash detrimental materials off the
vehicle promptly. If the residual
materials cannot be removed by soap
liquid, special cleaners can be used.
Caution
Only use safe cleaners that are not
detrimental to the painted surface.
Other cleaners can permanently
damage the paint.
Surface paint damage
Repair scrapes, cracks or deep scrat-
ches as soon as possible.
Exposed metal corrodes easily. Minor
cracks and scratches can be repaired by
using fast-drying products.
