Spots and stains
Tar stains, grease, oil spots and dead insects
cannot always be removed by washing alo-
ne. They can cause discoloration if allowed
to remain on the paintwork. They should
therefore be removed without delay with a
suitable cleaner (tar, stain or insect remo-
ver). Wash the affected area immediately af-
ter treating it.
Minor paint damage
Minor paint damage, such as scratches, sco-
res or chips caused by flying stones, should
be covered immediately with paint before
corrosion sets in. However, if there are alrea-
dy traces of corrosion they must first be re-
moved carefully and thoroughly. Coat the
area with a rust-proofing primer (applicator
or aerosol) and finish off with a top coat. The
paint code and color number are found on a
label close to lock on the left door pillar.
Undersealing
The underside of the car is durably protect-
ed by a factory-applied undersealing mate-
rial.
As it is not possible to exclude the risk of da-
mage to this protective coating in day-to-
day driving, it is advisable to have the under-
side of the car inspected at certain intervals
- preferably before the start of the cold sea-
son and again in the spring - and the under-
sealing repaired as necessary.
The oil industry has developed undersealing
and rust-proofing compounds based on bi-
tumen or wax. Unlike conventional spray
oils, these preservatives do not attack the
anti-drumming materials applied at the fac-
tory.
Before applying fresh underseal, carefully
remove deposits of dirt and grease. Once it
has dried the new undersealing compound
forms a tough protective coating which pro-
vides efficient rust-proofing of the floor pa-
nels and components.
Always apply a fresh coating of suitable
preservative to unprotected areas after
cleaning the underside of the body or the
engine or carrying out repairs to underbody
components.
Your Porsche dealer is familiar with the bo-
dyseal treatment procedures and has the
necessary equipment for applying factory-
approved materials. We recommend that
you entrust him with all such work and in-
spections.
Cleaning and preserving engine compart-
ment
The engine compartment and the surface of
the engine are treated with a corrosion inhi-
bitor at the factory. If grease solvents are
used for cleaning the engine compartment
or the engine itself, they invariably destroy
the corrosion inhibiting coating. It is then ab-
solutely necessary to have a durable preser-
vative applied to all surfaces, body seams,
joints and components in the engine com-
partment.
Grease the return springs of the accelerator
cable after every engine wash.
Effective rust-proofing is particularly impor-
tant during the cold weather season. If the
car is driven frequently in areas where salt
has been spread on the roads, the whole en-
gine compartment should be cleaned tho-
roughly after the cold weather season to
prevent the salt causing any lasting damage.
A full underbody wash should be performed
at the same time.
Windows
The road dust which settles on the wind-
shield and windows contains particles of tire
rubber and oil residue. The interior trim and
upholstery gives off deposits, particularly in
strong sunlight, which collect on the insides
of the windows. These deposits are aug-
mented by impurities in the air which enter
the car through the fresh air vents.
A luke-warm soap and water solution or a
normal window cleaner can be used for
cleaning the insides and outsides of win-
