CORROSION PROTECTION
Description
INFOID:0000000010843422
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 is adopted replacing conventional
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 parts are fabricated from galvannealed steel. Therefore, it is recommended that NISSAN
genuine parts or an equivalent be used for panel replacement to maintain the anti-corrosive performance 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 protection, are applied to
all body components.
CAUTION:
Confine paint removal during welding operation to an absolute
minimum.
NISSAN genuine parts are also treated in the same manner. Therefore, it is recommended that NISSAN gen-
uine parts or an equivalent be used for panel replacement to maintain anti-corrosive performance built into the
vehicle at the factory.
Undercoating
INFOID:0000000010860040
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 resistant, soundproof, vibration-proof, shock-resistant, adhesive, and durable.
Precautions in Undercoating
1.
Never apply undercoating to any place unless specified (such as the areas above the muffler and three
way catalyst that are subjected to heat).
2.
Never undercoat the exhaust pipe or other parts that become hot.
3.
Never undercoat rotating parts.
4.
Apply bitumen wax after applying undercoating.
5.
After putting seal on the vehicle, put undercoating on it.
