Inspect and clean out the drain
holes in the bottom of the doors
and body.
Check the floor coverings for
dampness. Carpeting and floor
mats may remain damp for a long
time, especially in winter. This
dampness can eventually cause
the floor panels to corrode.
Use a high-pressure spray to
clean the underside of your car.
This is especially important in
areas that use road salt in winter.
It is also a good idea in humid
climates and areas subject to salt
air. Cars equipped with ABS
have a sensor and wiring at each
wheel. Be careful not to damage
them.
Have the corrosion-preventive
coatings on the underside of your
car inspected and repaired
periodically.
Corrosion Protection, Body Repairs
Body Repairs
Body repairs affect your car's
resistance to corrosion. If your car
needs repairs after a collision, pay
close attention to the parts used in
the repair and the quality of the
work.
Make sure the repair facility uses
genuine Honda replacement body
parts. Some companies make
sheetmetal pieces that seem to
duplicate the original Honda body
parts, but are actually inferior in fit,
finish, and quality. Once installed,
they do not give the same high-
quality appearance and level of
corrosion resistance.
When reporting your collision to
the insurance company, tell them
you want genuine Honda parts
used in the repair. Although most
insurers recognize the higher
quality of original parts, some may
try to specify that the repairs be
done with the "lowest cost" parts
available. You should investigate
this before any repairs are begun.
Take your car to your authorized
Honda dealer for inspection after
the repairs are completed. He can
make sure that quality materials
were used, and that corrosion-
preventive coatings were applied to
all repaired and replaced parts.
