ANTICORROSION TREATMENT AT THE TIME OF
BODY REPAIR WORK
M4090020000046
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.
