CORROSION PROTECTION

TSB Revision

BASE OF BODY REPAIR

9-39

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.

CLEAN AWAY
ANY EXCESS

CORROSION PROTECTION

BASE OF BODY REPAIR

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.
