Corrosion ProtectionEIS002U5
DESCRIPTION
To provide improved corrosion prevention, the following anti-corrosive measures have been implemented in
NISSAN production plants. When repairing or replacing body panels, it is necessary to use the same anti-cor-
rosive measures.
ANTI-CORROSIVE PRECOATED STEEL (GALVANNEALED STEEL)
To improve repairability and corrosion resistance, a new type of anti-
corrosive precoated steel sheet has been adopted replacing conven-
tional zinc-coated steel sheet.
Galvannealed steel is electroplated and heated to form Zinc-iron
alloy, which provides excellent and long term corrosion resistance
with cationic electrode position primer.
Nissan Genuine Service Parts are fabricated from galvannealed steel. Therefore, it is recommended that
GENUINE NISSAN PARTS or equivalent be used for panel replacement to maintain the anti-corrosive perfor-
mance built into the vehicle at the factory.
PHOSPHATE COATING TREATMENT AND CATIONIC ELECTRODEPOSITION PRIMER
A phosphate coating treatment and a cationic electrode position primer, which provide excellent corrosion pro-
tection, are employed on all body components.
CAUTION:
Confine paint removal during welding operations to an absolute
minimum.
Nissan Genuine Service Parts are also treated in the same manner. Therefore, it is recommended that GENU-
INE NISSAN PARTS or equivalent be used for panel replacement to maintain anti-corrosive performance built
into the vehicle at the factory.

ANTI-CORROSIVE WAX
To improve corrosion resistance, anti-corrosive wax is applied inside the body sill and inside other closed sec-
tions. Accordingly, when replacing these parts, be sure to apply anti-corrosive wax to the appropriate areas of
the new parts. Select an excellent anti-corrosive wax which will penetrate after application and has a long shelf
life.

UNDERCOATING
The underside of the floor and wheelhouse are undercoated to prevent rust, vibration, noise and stone chip-
ping. Therefore, when such a panel is replaced or repaired, apply undercoating to that part. Use an undercoat-
ing which is rust preventive, soundproof, vibration-proof, shock-resistant, adhesive, and durable.
Precautions in undercoating
1. Do not apply undercoating to any place unless specified (such as the areas above the muffler and three
way catalyst which are subjected to heat).
2. Do not undercoat the exhaust pipe or other parts which become hot.
3. Do not undercoat rotating parts.
4. Apply bitumen wax after applying undercoating.
