Underbody Maintenance; Fiberglass Springs (Composite Springs); Chemical Paint Spotting - Chevrolet 2007 Corvette Owner's Manual

Underbody Maintenance

Chemicals used for ice and snow removal and dust
control can collect on the underbody. If these are
not removed, corrosion and rust can develop 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 debris can collect. Dirt packed in close
areas of the frame should be loosened before being
flushed. Your dealer or an underbody car washing
system can do this for you.
Fiberglass Springs
(Composite Springs)
Notice: If you use acidic or corrosive cleaning
products, engine degreasers or aluminum
cleaning agents on fiberglass springs, you
may damage the springs. The repairs would
not be covered by your warranty. Use only
approved cleaners when cleaning your
vehicle's fiberglass springs.

Chemical Paint Spotting

Some weather and atmospheric conditions can
create a chemical fallout. Airborne pollutants
can fall upon and attack painted surfaces on the
vehicle. This damage can take two forms: blotchy,
ring-shaped discolorations, and small, irregular
dark spots etched into the paint surface.
Although no defect in the paint job causes this,
we 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.
