joints and moisture-repelling asphaltic sound
deadeners are applied inside wheel wells and doors and
on some underbody components. Figures
15 through
23 illustrate typical production and field usage of these
materials.
Any procedure that disturbs these special
treatments, such as panel replacement or collision
damage repair operations, may leave the metal
unprotected and result in corrosion. Therefore, proper
recoating of these surfaces with service-type
anticorrosion material is essential.
Metal conditioners and primer coatings are
applied to all metal panels at the time of vehicle
manufacture. After repair and/or replacement parts
are installed, all accessible bare metal surfaces must be
treated with metal conditioner and
reprimed using an
acrylic chromate material. This operation is to be
performed prior to the application of sealers, waxes,
deadeners and antirust compounds.

Cleaning of interior and underbody panel
surfaces is necessary when original galvanized or other
anticorrosion materials have been burned off during
welding or heating operations. Removal of the residue
left from burning will require additional care in such
areas as interior surfaces of box-type construction and
when configurations of the metal panels limit access to
interior surfaces. One or more of the following methods
will remove the residue.
CAUTION: Standard shop practices,
particularly eye protection, should be
followed during these operations to
avoid personal injury.
Where access is possible, scraping can be used. If
a standard putty knife or scraper will not fit into
the affected area, consider fabricating a small,
flexible scraper from a narrow piece of sheet
metal.
e A jet of compressed air will remove most residue
and could be most effective in limited-access
areas. Eye protection is absolutely necessary in an
operation of this type.
e Sandblasting is most effective and should be used
when the equipment is available and access to the
area is good. Sandblasting is an excellent method
for cleanup and preparation of open joints,
underbody components and hem flange areas.
e Wire brushing (power and by hand).
e When access is good, sandpaper and steel wool
can be used.

Painting Flexible Parts - E/P or TPO
When painting flexible plastic exterior parts
identified as E/P or TPO, a polypropylene primer
must be used. Follow manufacturer's label
instructions.
METAL REPLACEMENWARTS
FINISHING
Metal service replacement parts (or assemblies)
are painted with a high-bake factory primer. For
proper adhesion of color coats in service, the following
refinish steps are necessary.
1. Clean part with a wax and grease-removing
solvent such as Prep-sol, Pre-Kleano,
Sher-Will-Clean, Acryli-Clean or equivalent.
2. Scuff-sand panel lightly with wet or dry no. 400
sandpaper and water. Avoid cut-throughs.
Reclean part. Apply sealer to entire part.
3. If factory primer coat was cut through, apply
metal conditioner to exposed bare metal. Follow
label directions.
4. Apply primer-surfacer to entire part; allow to dry
thoroughly before sanding. Follow label
directions for drying time.
5. Sand primer-surfacer using wet or dry no. 400
sandpaper and water. Do not sand sealer.
6. Reclean part.
7. Apply color coats to parts.
8. Follow label directions for drying time before
compounding.
9. Compound part by hand or with power
equipment.
10. Nonsealing polish may
be applied after rub-out if
desired. Waxes, however, should
not be applied
until the paint finish has aged at least two
months.
Prior to replacing exterior body parts or
assemblies, check condition of paint on all covered or
hidden interior surfaces.
If rust scale is found in these
areas, proceed as follows:
1. Remove rust with suitable wire brush, abrasive or
liquid rust removing agent. Follow label
directions.
2. If necessary, wash with detergent, rinse and dry.
3. Apply a heavy coating of anticorrosion
compound to all cleaned hidden surfaces before
installing exterior body parts. Also, apply
anticorrosion compound to all inner surfaces of
exterior body parts being installed.
INTERIOR PLASTBC TRIk7 PARTS
FINISHING
Paintable plastic interior trim components can be
divided into three general types:
Polypropylene Plastic
@ ABS Plastic
e Vinyl Plastic
It is important for a painter to be able to identify
each plastic in order to paint it satisfactorily. Painting
of complete soft seat cushion and
seatback trim cover
assemblies of vinyl construction is not approved by the
factory. Excluding the soft seat cushion and seat back
trim cover assemblies, the plastic used most widely on
the interior of bodies is polypropylene.
The purpose of the following tests is to determine
the identity of a given plastic so that proper paint
procedures and materials can be used.
Pest for Polypropylene and ABS Plastic
To determine if a service part to be painted is
polypropylene or
ABS plastic, perform the following
burn test:
1. From a hidden backside portion of the part,
remove a sliver of plastic with a sharp blade.
2. While holding the sliver of plastic with tweezers
or laying it on a clean noncombustible surface,
ignite the plastic.
3. Observe the burning plastic closely:
a. Polypropylene burns with no readily visible
smoke.
b. ABS plastic burns with a readily visible
black smoke residue which hangs
temporarily in the air.
Pest for Vinyl Plastic
To determine if a part to be painted is vinyl plastic
(polyvinyl chloride), a copper wire test should be
performed as follows:
1. Heat a copper wire in a suitable flame such as
provided by a propane or equivalent torch until
the wire glows (turns red).
2. Touch the heated wire to the backside or hidden
surface of the part being
testsd in a manner so as
to retain some of the plastic on
the wire.
3. Return the wire (and retained plastic) to the
flame and observe for a green, turquoise blue
flame. A flame in this color range indicates that
the plastic being tested is vinyl.
4. If black smoke residue, which hangs temporarily
in the air, is readily visible when wire (with
retained plastic residue) is returned to the flame,
the part is made of flexible (soft)
ABS plastic
material.
PAINTING POLYPROPYLENE PLASTIC PARTS
The system for painting polypropylene parts
involves the use of a special primer. Since
polypropylene plastic is hard, it can be
color coated
after prime with conventional interior acrylic lacquer.
