Apply paint preservative after the car wash and
polish it dry to obtain a bright finish.
Polishing
Do not resort to using Porsche polish until it
becomes evident that the normal preservatives
no longer produce the desired finish.
Spots and stains
Remove tar stains, grease, oil spots and
dead insects as soon as possible with Insect
Remover. They can cause discoloration if
allowed to remain on the paintwork.
Wash the affected area immediately after
treating it.
Minor paint damage
Have minor paint damage, such as scratches,
scores or chips caused by flying stones,
repaired immediately by your authorized
Porsche dealer before corrosion sets in.
However, if there are already traces of corrosion,
they must first be removed carefully and thorough-
ly. Coat the area with a rust-proofing primer and
finish off with a top coat. The paint code and color
number are found on the data bank in the Mainte-
nance booklet and on the filler flap.
Engine compartment
The engine compartment and the surface of the
engine are treated with a corrosion-inhibitor at the
factory.
If degreasing solvents are used to clean the
engine compartment or the engine is washed
down, the process almost invariably removes the
corrosion-inhibiting coating. It is then absolutely
necessary to have a durable preservative applied
to all surfaces, body seams, joints and assemblies
in the engine compartment. This also applies when
corrosion-inhibitor parts are replaced.
Caution!
Risk of damage to the alternator.
Do not point the cleaning jet directly at the
alternator, or cover the alternator.
Effective corrosion-proofing is particularly impor-
tant during the cold weather season. If your car
is driven frequently in areas where salt has been
spread on the roads, the whole engine compart-
ment should be cleaned thoroughly after the winter
to prevent salt from causing any lasting damage. A
full under-body wash should also be performed at
the same time.
Windows
The road dust which settles on the windshield
and windows contains particles of tire rubber
and oil residue. The interior trim and upholstery
release particles, particularly in strong sunlight,
which collect on the insides of the windows. These
deposits are augmented by impurities in the air
which enters the car through the fresh air vents.
Clean all windows regularly, inside and outside,
with Porsche window cleaner.
If you use a chamois leather for the windows,
do not use it for paintwork as it will otherwise
pick up a certain amount of preservative or
polish and could smear the windows and thus
impair vision.
Remove dead insects with Porsche insect
remover.
Note
Door windows feature a water-repellent (hydropho-
bic) coating which prevents soiling of the windows.
This coating is subject to natural wear and can be
renewed.
Consult an authorized Porsche dealer.
Wiper blades
Wiper blades that are in perfect condition are vital
for a clear view.
Replace the wiper blades twice per year
(before and after the cold season) or whenever
wiper performance deteriorates.
