Finish Damage
Any stone chips, fractures or deep
scratches
in the finish should be repaired
right away.
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 vehicle washing
system can do this for you.

Fiberglass Springs
I NOTICE:
Don’t use corrosive or acidic
cleaning agents, engine degreasers,
aluminum cleaning agents or other
harsh solvents to clean fiberglass
springs; they’ll damage the springs.
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, Chevrolet 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)
Df purchase, whichever comes first.
