Finish Damage
Any stone chips, fractures or deep scratches in the finish
should be repaired right away. Bare metal
will
corrode
quickly and may develop into a major repair expense.
Minor chips and scratches can be repaired with touch-up
materials available from your dealer or other service
outlets. Larger areas of finish damage can be corrected
in your dealer’s body and paint shop.
Underbody Maintenance
Chemicals used for ice and snow removal and dust
control can collect
on
the underbody. If these are
not
removed, accelerated corrosion (rust) can occur on
the
underbody
parts
such
as
fuel
lines, frame, floor
pan and exhaust system even though they have
corrosion protection.
At least every spring,
flush
these materials from
the
underbody with plain water. Clean any areas where mud
and other debris can collect. Dirt packed
in
closed areas
of the frame should be loosened before being flushed.
Your dealer or an underbody car washing system can do
this for
you.
Chemical
Paint Spotting
Some weather and atmospheric conditions can create
a
chemical fallout. Airborne pollutants can fall upon
and attack painted surfaces
on
your vehicle. This
damage can take two forms: blotchy, ringlet-shaped
discolorations, and small irregular dark spots etched
into the paint surface.
Although no defect
in
the paint job causes this,
GM
will repair, at
no
charge to the owner, the surfaces of
new vehicles damaged by this fallout condition within
12
months or
12,000
miles
(20
000
km) of purchase,
whichever occurs first.
