WAX INJECTION

Wax injection is used at the lower part of the frame, side sill and
hollow panels, etc., in order to obtain a better anticorrosion
effect.

ANTICORROSION PRIMER

Anticorrosion primer is used at the side sill outer pan-
els in order to prevent corrosion and to suppress
vibration.

SEALING TAPE

Sealing tape is attached at unused holes, at the inner side of
the panel, for waterproofing and anticorrosion protection.

ANTICORROSION TREATMENT AT THE TIME OF
BODY REPAIR WORK

M4090020000024

The following procedures should be followed for anticorrosion
protection when making repairs.

CORROSION PROTECTION FOR HOLLOW
PARTS

CAUTION

•

Wipe away any excess anticorrosion agent on the
coated surface, because it can adversely affect the
coating.

•

When spraying the anticorrosion agent, use holes in
different areas to ensure that all weld surfaces of the
hollow structure are well coated.

The insides of hollow parts (such as the side sill, pillars, etc.)
which have been welded are more susceptible to corrosion.
Spray an aerosol-type anticorrosion agent into these parts by
using the trim mounting holes and other openings.

ANTICORROSION TREATMENT OF ROUGH CUTS

An anticorrosion agent should be applied to rough cuts made in
the course of welding, because the surface film has been dam-
aged by the heat of welding.

SPOT SEALER

In order to prevent corrosion from occurring at the contact sur-
faces of panels which are spot welded, apply an electroconduc-
tive spot sealer.

.

SPOT SEALER APPLICATION STEPS
1. Remove all paint, etc., from the areas to be spot welded by

using sandpaper or a pneumatic belt sander.

2. Use a brush to apply spot sealer to the contact surfaces of

the panels (both the new panel and the panel remaining on
the body) to be spot welded.

3. Do not spot welding.

NOTE: The spot welding can be done as the spot sealer is
dry to the touch.
Dry to the touch: 30 minutes or less at 20

BODY SEALING

Even if a car body is restored to the exact specified dimen-
sions, the body repair work cannot be considered to be com-
plete if an ample amount of sealant is not applied to each of the
panel joints and seams. Insufficient sealant will result in water
leakage, corrosion, etc.
NOTE: Use a piece of clean cloth dampened in lead-free gaso-
line or a similar material to clean parts and areas where sealant
is applied.

•

When applying sealant to areas at which the external
appearance is important (areas which can be seen or where
the condition of the paint coat is important), be sure to apply
the sealant so that it is perfectly level with the surrounding
panels.

•

Apply the sealant at the fuel port so that it is perfectly level
with the surrounding panel so that drops of fuel will not col-
lect.

•

After applying sealant to the door-stop, etc., clean away any
excess so as to be sure that there is no interference with
installed parts, etc.

UNDERCOATING

•

Be sure to mask any parts installation holes, and
the area around the place where undercoating is
to be applied, before applying it.

•

Be sure not to apply the undercoating to tires or
to the drive shaft and other drive components.

If the undercoating application inside the wheel
housing, on the under body, etc., is insufficient, it can
result in corrosion. Be sure, therefore, to apply a
good coating of undercoating to such parts after
repairs are completed.
