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 at~nospheric 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, Buick
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 comes first.
