started by observing the following:

exposed to corrosive materials, corrosion pro-
tection is  particularly important. Some of   the

Protecting Your  Hyundai from  Corro-
sion
Moisture creates the conditions in which corro-
sion is most likely to occur. For example, corro-
sionisacceleratedbyhighhumidity,particularly
when temperatures are just above freezing. In

Mudisparticularycorrosivebecauseitisslowto
dry and holds moisture in contact  with the ve-
hicle.Althoughthemudappearstobedry,itcan
still retain the moisture and promote corrosion.
High temperatures can  also accelerate corro-
sion of parts that are not properly ventilated so
the moisture can  be dispersed.  For  all these
reasons, it is particularly important to keep your
car clean and free of mud or accumulations of
other  materials. This  applies not  only  to the
visiblesurfacesbutparticularlytotheunderside
of the car.

If you live in a high-corrosion area — where
road salts are used, near the ocean, areas
withindustrialpollution,acidrain,etc.—,you
should take extra care to prevent corrosion.

Removal of paint or  protective coatings by
stones, gravel,  abrasion or  minor scrapes
and dents  which leave  unprotected  metal
exposed to corrosion.

When cleaning  lower  door panels,  rocker
panels and  frame  members, be  sure that
drain holes are kept open  so that moisture
can escape and not be trapped inside to ac-
celeratecorrosion.
