ANTI-CORROSION TREATMENT
Steel sheets used for vehicles are provided with corro-
sion resistance on its either side or both sides as rust
proof treatment. These corrosion resistance steel
sheet materials are called one or two-side galvanized
steel sheets. They are selected for their rust protection
property and further given various types of treatment
depending on where they are used as described be-
low.
Steel sheets are treated with cathodic electroprimer
which is excellent in corrosion resistance.
Rust proof wax coatings are applied to door, front
hood and side sill insides where moisture is liable
to stay.
Vinyl coating or asphalt coating is applied to body
underside and wheel housing inside.
Chip resistant material is applied to side sill and
door outside bottom areas to protect painted sur-
face from damage due to flying stones.
Sealer is applied to door hem, engine compartment
steel sheet-to-steel sheet joint, and the like portions
to prevent water penetration which results in rust
occurrence.
When replacing panel or repairing collision damage,
leaving related area untreated as it is in any operation
which does disturb any rust proof treatment described
above will allow corrosion in that area. Therefore, it is
important in any repair operation to properly recoat
surface of related area.
Accordingly, it is the essential function of any repair
operation to correctly recoat the related surfaces of
the relevant area.
All metal panels are coated with metal conditioners
and primer coating during vehicle production. Follow-
ing repair and/or replacement parts installation, every
accessible bare metal surface should be cleaned and
coated with rust proof primer. Perform this operation
prior to application of sealer, rust proof wax coating
and chip resistant material.
Sealer is applied to specific joints of a vehicle during
production. It prevents dust from entering vehicle and
serves also as an anticorrosive barrier. Sealer is ap-
plied to door and hood hem areas and between panels
as well. Correct and reseal originally- sealed joints if
damaged. Reseal attaching joints of a new replace-
ment panel and reseal hem area of a replacement
door or hood.
Use a quality sealer to seal flanged joints, overlap
joints and seams. Sealer must have flexible character-
istics and paintability after it's applied to repair areas.
For sealer to fill open joints, use caulking material. Se-
lect a sealer according to place and purpose of a spe-
cific use. Observe
instructions when using sealer.
In many cases, repaired places require color painting.
If so, follow ordinary techniques specified for finish
preparation, color painting and undercoating build-up.
Rust proof wax, a penetrative compound, is applied to
metal-to-metal surfaces (door, front hood and side sill
insides) where it is difficult to use ordinary undercoat-
ing material for coating. Therefore, when selecting
rust proof wax, it may be one of such penetrative type.
During undercoating (vinyl coating or asphalt coating)
application, care should be taken that sealer is not ap-
plied to engine-related parts and shock absorber
mounting or rotating parts. The following undercoat-
ing, make sure that body drain holes are kept open.
Anticorrosive materials.
1) Clean and prepare metal surface.
2) Apply primer.
3) Apply sealer (all joints sealed originally).
4) Apply chip-resistant material (side sill and door out-
side bottom areas).
5) Apply color in areas where color is required such
as hem flanges, exposed joints and under body
components.
6) Apply anticorrosive compound (penetrative wax).
7) Apply undercoating (rust proof material).
