Removing spots and stains
f Remove tar spatters, traces of oil, insects etc.
as soon as possible with an insect remover, as
they discolour the paint if left to work on it over
time.
f
Carefully wash the treated areas again.
Minor paint damage
f
Have minor paint damage (cracks, scratches
or stone damage) repaired immediately
before
corrosion begins.
Consult a qualified specialist workshop. We
recommend a Porsche partner for this work as
they have trained workshop personnel and the
necessary parts and tools.
If corrosion has already formed, it must be
thoroughly removed. An anti-corrosion primer is
then applied, followed by top coat paint.
Paint data can be found on the vehicle’s data bank.
Cleaning and preserving engine
compartment
The engine compartment and the surface of the
engine are treated with a corrosion inhibitor at the
factory.
If grease 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-protected parts are replaced.
Caution!
Risk of damage to generator.
f Do not point the cleaning jet directly at the
generator, or cover the generator.
Effective rust-proofing is particularly important
during the cold weather season. If the car is driven
frequently in areas where salt has been spread on
the roads, the whole engine compartment should
be cleaned thoroughly and subsequently sealed
after the cold weather season to prevent salt from
causing any lasting damage.
Windows
f
Clean all windows regularly, inside and out,
with window cleaner.
We recommend the Porsche window cleaner.
Do not use the same leather for painted
surfaces and for drying the windows.
Preservative residues could reduce transpar-
ency.
f
Remove insect residues with insect remover.
Note
Door windows feature a water-repellent (hydro-
phobic) coating which prevents soiling of the
windows.
This coating is subject to natural wear and can be
renewed.
f Consult a qualified specialist workshop. We

necessary parts and tools.
