8. Maintenance of body exterior
Body exterior is to keep body cleanness and brightness to give the impression of beauty and comfort, and to avoid
rust and abnormal paint peeling off. The key points of body maintenances are:
(1) Wash body using the method below:
a. Wash the dirty things off the body by pressurized water, and then clean the body with
soft cloth of sponge from up to down.
b. Dry body surface with good white cloth. Apply brake pedal several times when driving
after the car is washed to get rid of water in braking system.
c. Do not wipe the body when it is dry. Do not clean paint surface and glass with gasoline,
coal oil, narkosid, strong lye or alcohol.
(2) Cleaning windshield glass
Do not use silicon-bronze radical products. To get better cleaning effects, use special glass cleanser.
(3) Cleaning asphalt on the body
Do not peel the asphalt off from body or bumper, but use special cleanser
(4) Paint
Scratches or slight damages can be fixed with special paint spray. It dries in the air.
(5) Cleaning exterior decoration parts and aluminum parts. Wash with water with soap fluid or cleanser, and wash with clean water. To keep the gloss of painted surface,
wax on the surface after it is dry. (6) Polish and wax the body paint polishing and waxing keeps the body bright and pretty, and protects the paint
as well.
a. Polish in winter. Make sure the vehicle body is absolutely clean and dry before
polishing, polish with fluid or milky wax.
b. Vehicle body must be absolutely dry and clean before waxing. Use waxing tools (soft
table tissue or smooth cotton cloth) to cover the body paint surface evenly with wax.
Check if the vehicle body is covered by wax: spray some water onto the paint surface,
if water drops are formed, that surface is waxed, otherwise, clean the surface and wax
it again. Attention: do not wax under sun, or in cold weather.
Attention
1) When using high pressure washing machine, do not point the washing sprayer to transmission, steering
mechanism and other rubber protection parts, or exterior decoration parts, roof welding lines, heat radiator
or engine compartment.
2) The bottom of vehicle body is made of anti-corrosion material,and has been through anti-corrosion process.
After the vehicle has been running frequently on roads de-frozen with salt for some time, clean engine
compartment and lower part of vehicle body and take some protection actions.Usage and Maintenance of MK Series - Daily Maintenance of MK Sedan
