Corrosion Protection

NIS0020Z

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 electrodeposition 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 electrodeposition 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.

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

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).

Do not undercoat the exhaust pipe or other parts which become hot.

Do not undercoat rotating parts.

Apply bitumen wax after applying undercoating.

After putting seal on the vehicle, put undercoating on it.

Body Sealing

NIS00210

DESCRIPTION

The following figure shows the areas which are sealed at the factory. Sealant which has been applied to these
areas should be smooth and free from cuts or gaps. Care should be taken not to apply an excess amount of
sealant and not to allow other unaffected parts to come into contact with the sealant.
