cle. Even though the mud appears to be dry, it can still retain moisture and promote corrosion.
High temperatures can also accelerate corrosion of parts that are not properly ventilated so the moisture can be dis
鄄
persed. 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 on the visible surfaces but particularly to the underside of the car.
TO HELP PREVENT CORROSION
You can help prevent corrosion from getting started by observing the following:
Keep Your Car Clean
The best way to prevent corrosion is to keep your car clean and free of corrosive materials. Attention to the underside of
the car is particularly important.
●
If you live in a high -corrosion erea where road salts are used, near the ocean, areas with industrial pollution, acid
rain, etc. You should take extra care to prevent corrosion. In winter, hose off the underside of your car at least once a
month and be sure to clean the underside thoroughly when winter is over.
●
When cleaning underneath the car, give particular attention to the components under the fenders and other areas that
are hidden from view. Do a thorough job; just dampening the accumulated mud rather than washing it away will accel
鄄
erate corrosion rather than prevent it. Water under high pressure and steam are
particularly effective in removing ac
鄄
cumulated mud and corrosive materials.
●
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 accelerate corrosion.

PROTECTING YOUR JAC FROM CORROSION
By using the most advanced design and construction practices to combat corrosion, JAC produces cars of the highest
quality. However, this is only part of the job. To achieve the long-term corrosion resistance your JAC can deliver, the
owners cooperation and assistance is also required.
Common Causes of Corrosion
The most common causes of corrosion on your car are:
●
Road salt, dirt and moisture that is allowed to
accumulate underneath the car.
●
Removal of paint or protective coatings by stones, gravel, abrasion or minor scrapes and dents which leave unpro
鄄
tected metal exposed to corrosion.
High-Corrosion Areas
If you live in an area where your car is regularly exposed to corrosive materials, corrosion protection is particularly im
鄄
portant. Some of the common causes of accelerated corrosion are road salts, dust control chemicals, ocean air and in
鄄
dustrial pollution.
Moisture Breeds Corrosion
Moisture creates the conditions in which corrosion is most likely to occur. For example, corrosion is accelerated by high
humidity, particularly when temperatures are just above freezing. In such conditions, the corrosive material is kept in
contact with the car surfaces by moisture that is slow to evaporate.
Mud is a particular enemy of corrosion protection because it is slow to dry and holds moisture in contact with the vehi
