PAINT AND COATINGS .................................. 9-50 WARNING:
For vehicles equipped with Supplemental Restraint (Air Bag) System:
Service on and around the air bag system components or wiring must be performed only by an
authorized SUZUKI dealer. Refer to “Air Bag System Components and Wiring Location View” under
“General Description” in air bag system section in order to confirm whether you are performing ser-
vice on or near the air bag system components or wiring. Please observe all WARNINGS and “Ser-
vice Precautions” under “On-Vehicle Service” in air bag system section before performing service
on or around the air bag system components or wiring. Failure to follow WARNINGS could result in
unintentional activation of the system or could render the system inoperative. Either of these two
conditions may result in severe injury.
Technical service work must be started at least 90 seconds after the ignition switch is turned to the
“LOCK” position and the negative cable is disconnected from the battery. Otherwise, the system
may be activated by reserve energy in the Sensing and Diagnostic Module (SDM).
When body servicing, if shock may be applied to air bag system component parts, remove those
parts beforehand. (Refer to Section 10B.)
NOTE:
Fasteners are important attaching parts in that they could affect the performance of vital components
and systems, and / or could result in major repair expense. They must be replaced with one of the
same part number of with an equivalent part if replacement becomes necessary.
Do not use a replacement part of lesser quality or substitute a design. Torque values must be used as
specified during reassembly to assure proper retention of these parts.

PAINT AND COATINGS
ANTI-CORROSION TREATMENT
As rust proof treatment, steel sheets are given corrosion resistance on the interior and/or exterior.
These corrosion resistance steel sheet materials are called one of two-side galvanized steel sheets.
It is for the sake of rust protection that these materials are selected and given a variety of treatments as
described blow.
Steel sheets are treated with cathodic electroprimer which is excellent in corrosion resistance.
Rust proof wax coatings are applied to door and side sill insides where moisture is liable to stay.
Vinyl coating is applied to body underside and wheel housing inside.
Sealer is applied to door hem, engine compartment steel sheet-to-steel sheet joint, and the like portions to
prevent water penetration and resulting in rust occurrence.
In panel replacement or collision damage repair, leaving the relevant area untreated as it is in any operation
which does disturb the above-mentioned rust proof treatment will cause corrosion to that area. Therefore, it is
the essential function of any repair operation to correctly recoat the related surfaces of the relevant area.
All the metal panels are coated with metal conditioners and primer coating during vehicle production. Following
the 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 the application of sealer and rust proof wax coating.
Sealer is applied to the specific joints of a vehicle during production. The sealer is intended to prevent dust from
entering the vehicle and serves also as an anticorrosion barrier. The sealer is applied to the door and hood hem
areas and between panels. Correct and reseal the originally sealed joints if damaged. Reseal the attaching
joints of a new replacement panel and reseal the hem area of a replacement door or hood.
Use a quality sealer to seal the flanged joints, overlap joints and seams. The sealer must have flexible character-
istics and paint ability after it’s applied to repair areas.
For the sealer to fill open joints, use caulking material. Select a sealer in conformance with the place and pur-
pose of a specific use. Observe the manufacturer’s label-stand instructions when using the sealer.
In many cases, repaired places require color painting. When this is required, follow the ordinary techniques
specified for the finish preparation, color painting and undercoating build-up.
Rust proof wax, a penetrative compound, is applied to the metal-to-metal surfaces (door and side sill insides)
where it is difficult to use ordinary undercoating material for coating. Therefore, when selecting the rust proof
wax, it may be the penetrative type.
During the undercoating (vinyl coating) application, care should be taken that sealer is not applied to the engine-
related parts and shock absorber mounting or rotating parts. Following the under coating, make sure that body
drain holes are kept open.
The sequence of the application steps of the anti-corrosion materials are as follows:
1) Clean and prepare the metal surface.
2) Apply primer.
3) Apply sealer (all joints sealed originally).
4) Apply color in areas where color is required such as hem flanges, exposed joints and under body compo-
nents.
5) Apply anticorrosion compound (penetrative wax).
6) Apply undercoating (rust proof material).WARNING:
Standard shop practices, particularly eye protection, should be followed during the performance of the
below-itemized operations to avoid personal injury.

BODY SERVICE 9-61
PLASTIC PARTS FINISHING
Paintable plastic parts are ABS plastic parts.
Painting
Rigid or hand ABS plastic needs no primer coating.
General acrylic lacquers can be painted properly over hard ABS plastic in terms of adherence.
1) Use cleaning solvent for paint finish to wash each part.
2) Apply conventional acrylic color lacquer to part surface.
3) Follow lacquer directions for required drying time. (Proper drying temperature range is 60 – 70 °C (140 – 158
°F)).
Reference
Plastic parts employ not only ABS (Acrylonitrile Butadiene Styrene) plastic but also polypropylene, vinyl, or the
like plastic. Burning test method to identify ABS plastic is described below.
1) Use a sharp blade to cut off a plastic sliver from the part at its hidden backside.
2) Hold sliver with pincers and set it on fire.
3) Carefully observe condition of the burning plastic.
4) ABS plastic must raise readily distinguishable back smoke while burning with its residue suspended in air
temporarily.
5) Polypropylene must raise no readily distinguishable smoke while burning.

SERVICE PRECAUTIONS
SERVICE AND DIAGNOSIS
Before servicing or replacing seat belts, refer to following precautionary items.
Seat belts should be normal relative to strap retractor and buckle portions.
Keep sharp edges and damaging objects away from belts.
Avoid bending or damaging any portion of belt buckle or latch plate.
Do not bleach or dye belt webbing. (Use only mild soap and lukewarm water to clean it.)
When installing a seat belt anchor bolt, it should be tightened by hand at first to prevent cross-threading and
then to specified torque.
Do not attempt any repairs on retractor mechanisms or retractor covers. Replace defective assemblies with
new replacement parts.
Keep belts dry and clean at all times.
If there exist any parts in question, replace such parts.
Replace belts whose webbing is cut or otherwise damaged.
Do not put anything into trim panel opening which seat belt webbing passes through.
