Door lock
f To prevent the door lock from freezing during
the cold season, the lock cylinder should be
covered during a wash.
f Should the lock freeze, use an ordinary de-icer.
In many cases, a well warmed key can help.
Never use excessive force.
Paint
To protect the paint on your vehicle in the best
possible way against mechanical and chemical
damage, you should
– preserve it regularly,
– polish it if necessary,
– remove spots and stains, and
– repair damaged paintwork.
f Do not apply care products containing silicone
to the convertible top and windows.
General information
f Never rub a dusty vehicle with a dry cloth,
because the grains of dirt will damage the
paintwork.
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.
f Preserve paint regularly.
f Apply paint preservative after washing the
vehicle and polish it smooth to preserve the
paintwork.
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.
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 Have minor paint damage, such as scratches,
scores or chips caused by flying stones, re-
paired 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.
f Please see the chapter "VEHICLE DATA BANK"
on Page 264.
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.
