Corrosion Protection
INFOID:0000000005274691
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 Pre-coated Steel (Galvannealed Steel)
To improve repairability and corrosion resistance, a new type of anti-
corrosive pre-coated steel sheet has been adopted replacing con-
ventional 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-cor-
rosive performance 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 protection, are employed
on all body components.
NISSAN Genuine Service Parts are also treated in the same man-
ner. Therefore, it is recommended that GENUINE NISSAN PARTS
or equivalent be used for panel replacement to maintain anti-corro-
sive performance built into the vehicle at the factory.
CAUTION:
Confine paint removal during welding operations to an absolute
minimum.
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.

CORROSION PROTECTION
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.
