Paint
f Never rub a dusty car with a dry cloth since
dust particles are abrasive and could dull and
damage the surface finish.
The paintwork of your car is exposed to all types
of mechanical and chemical conditions, particular-
ly climatic ones such as bright sunlight, rain, frost
and snow. Ultraviolet light, rapid changes in tem-
perature, rain, snow, industrial dust and chemical
deposits constantly attack the paint which is only
able to withstand such exposure in the long term
if it is given regular care and attention.
f Do not apply silicone polishes to the windshield
or window.
f Do not treat matt-painted components with
preservatives or polishes, otherwise the matt
effect will be lost.
Preservation
The paint surface becomes dull over time due to
weathering. It is therefore necessary to preserve
the paint regularly.
This keeps the paint shiny and elastic. Dirt is
prevented from adhering to the paint surface and
industrial dust is prevented from penetrating the
paint.
Provided it is washed and treated with preserva-
tive regularly, the brand new finish of your car will
be retained for years to come.
f Simply apply paint preservative after washing
the car and polish it smooth.
Polishing
Do not resort to using Porsche polish until it
becomes evident that the normal preservatives no
longer produce the desired finish.
Removing spots and stains
f Remove tar stains, grease, oil spots and dead
insects etc. as soon as possible with Insect Re-
mover. They can cause discoloration if allowed
to remain on the paintwork.
f Wash the affected area immediately after
treating it.
Minor paint damage
f Have minor paint damage, such as scratches,
scores or chips caused by flying stones,
repaired immediately by your authorized
Porsche dealer before corrosion begins.
However, if there are already traces of corrosion,
they must first be removed carefully and
thoroughly. 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 Maintenance booklet and on the vehicle's
data bank.
f Please see the chapter "DATA BANK" on
Page 350.
Cleaning the engine compartment
Caution!
Risk of damage, e.g. to the alternator,
painted surfaces, and the valve covers.
f Never use high-pressure cleaning units with a
round-jet nozzle.
f Always maintain a minimum distance of 21 in.
(50 cm).
f Always cover the lid over the brake fluid reser-
voir prior to cleaning with a high-pressure
cleaner. Never point the cleaning jet directly at
the lid.
f Do not point the cleaning jet directly at any of
the aforementioned components.
Note on operation
If the car is driven off-road frequently and after
driving on salted or gritted roads:
f Clean the engine compartment regularly.
