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 pre-
vented from adhering to the paint surface and in-
dustrial 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 Apply the Porsche paint preservative after the
car wash and polish it dry to obtain a bright fin-
ish or simply add a liquid preservative regularly
to the final rinse water.
Polishing
Do not resort to using Porsche polish until it be-
comes evident that the normal preservatives no
longer produce the desired finish.
Spots and stains
f Remove tar stains, grease, oil spots and dead
insects as soon as possible with Insect Remov-
er. They can cause discoloration if allowed to
remain on the paintwork.
f Wash the affected area immediately after treat-
ing it.
Minor paint damage
f The special features of carbon fiber
technology require that checking and damage
analysis on the chassis and body (e.g. after
accidents) must only be performed by your
authorized Porsche dealer.
f Have minor paint damage (cracks, scratches
or stone damage) repaired immediately by
your authorized Porsche dealer.
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 en-
gine compartment or the engine is washed down,
the process almost invariably removes the corro-
sion-inhibiting coating. It is then absolutely neces-
sary 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.
f Do not point the cleaning jet directly at the al-
ternator, or cover the alternator.
f Do not point the cleaning jet directly at the
intake openings. Water can enter the intake
system.
f Do not point the cleaning jet directly at the
transmission vent. Water can enter the
transmission.
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 win-
ter to prevent salt from causing any lasting dam-
age. A full under-body wash should also be per-
formed at the same time.
