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, Cadillac
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.
