9-70 BODY SERVICE
If original galvanization or other anticorrosive material
on interior and underbody panel surfaces is burnt dur-
ing welding or heating operation, affected surfaces
must be cleaned.
Burnt residues should be removed carefully when af-
fected area is in box-type construction or in such
shape as to limit access to interior surfaces. Generally,
following method works out satisfactorily in removing
such residues.
NOTE:
Standard shop practices, particularly eye protec-
tion, should be followed during performance of
above-listed operations to avoid personal injury.
Scrape any accessible area. If affected area is en-
closed by sheet metals and a standard putty knife or
scraper cannot reach there, try to use a more flexible
scraper. Compressed air can remove most residues
and is useful in cleaning enclosed areas. However,
this type of operation absolutely requires eye protec-
tion.
METAL REPLACEMENT PARTS
FINISHING
Metal replacement parts (or assemblies) are coated
with electro-deposition primer. For proper adhesion of
paint, the following finish process (refinish steps) be-
comes necessary.
1) Use wax or grease-removing solvent to clean each
part.
2) Use a wet or dry sand-paper (No.400) to polish
panel lightly. Do not polish it forcibly to produce any
scratch. Clean each part again.
3) If factory-applied primer coating is cut through to
bare metal, apply metal conditioner to bare metal
exposed to open air. As for the method of use of the
metal conditioner, follow directions on its container.
4) Apply primer-surfacer to the part completely dry
before starting sand-paper polishing. As for dry-
ing time, follow directions advised on primer-sur-
facer container.
5) Use a wet or dry sand-paper (No.400) and water
to polish panel lightly.
6) Wash part again.
7) Apply color coating to part.
8) Different paints demand different drying methods.
Hence, follow directions advised on pertinent
paint container.
9) When lacquer coating (quick-drying paint coat-
ing) is applied, dry coated surface and polish it
with compound.
In the case of melamine or acrylic coating, com-
pound polishing can be omitted after drying.
l0) In the case of lacquer coating, wax should not be
applied to coated surface until surface has dried
completely (for approximately 2 months).
Before replacing exterior parts or assemblies, check
paint conditions of all covered or hidden interior sur-
faces. If any rust scale is found at these places, pro-
ceed as follows:
1) Use a proper wire brush, adhesive or liquid rust re-
moving agent to remove rust. As for method of use,
follow directions advised for respective materials.
2) If necessary, wash parts with detergent, rinse, and
dry them.
3) Before installing exterior body parts, apply anticor-
rosive compound to all cleaned surfaces of exterior
body parts. Also, apply anticorrosive compound to
inner surfaces of exterior body parts to be installed.
