Maintenance
damage to the protective coating
and cause discoloration or paint
deterioration.
Finish damage repair
Deep scratches or stone chips in the
painted surface must be repaired
promptly. Exposed metal will quickly
rust and may develop into a major
repair expense.
NOTICE
If your vehicle is damaged and
requires any metal repair or
replacement, be sure the body shop
applies anti-corrosion materials to
the parts repaired or replaced.
Bright-metal maintenance
To remove road tar and insects, use
a tar remover, not a scraper or
other sharp object.
To protect the surfaces of bright
metal parts from corrosion, apply a
coating of wax or chrome preserva -
tive and rub to a high luster.
During winter weather or in coastal
areas, cover the bright metal parts
with a heavier coating of wax or
preservative. If necessary, coat the
parts with non-corrosive petroleum
jelly or other protective compound.
Underbody maintenance
Road salt and other corrosive chem -
icals are used in cold weather states
to melt snow and prevent ice accu -
mulation. If these chemicals are not
regularly removed, they will corrode
the vehicle underbody and, over
time, damage many parts: the fuel
lines, the fuel tank retention sys -
tem, the vehicle's suspension, the
exhaust system, and even the body
frame.
The National Highway Traffic Safety
Administration has warned all vehi -
cle owners of all brands of the need
to take the following steps:
Wash the undercarriage of your
vehicle regularly during the winter
and whenever your vehicle has
been exposed to such salts or
chemicals.
Do a thorough washing of the
undercarriage at the end of the
winter.
Use professional service techni -
cians or governmental inspection
stations to annually inspect for
corrosion.
Immediately seek an inspection of
your vehicle if you become visu -
ally aware of corrosion flaking or
scaling or if you become aware of
a change in vehicle performance,
such as soft or spongy brakes,
fluids leaking, impairment of
directional control, suspension
noises or rattling metal straps.
