3B-2 METAL REPAIR AND PAINTING
Extend coating at least three inches beyond heated or
drilled areas and allow to dry.
AMC Rustprooflng
Whenever the factory petroleum base wax has been
removed from a body panel, it is necessary to apply
AMC Rustproofing to these areas using the following
procedure:
(1) Shake aerosol container to mix contents
thoroughly.
(2) Hold aerosol container 10 to 14 inches from
panel area to be coated and spray panel until desired
coverage is achieved.
NOTE: Apply the rustproofing material in a coating
that is thick enough to cover the panel repair area com
pletely. Metal must not show through the coating.
(6) Invert aerosol container and spray to clean aero
sol container valve.
PAINT REPAIR WITH ACRYLIC ENAMEL
Recent advancements in acrylic enamels have pro
duced a repair procedure which can be used to effec
tively spot repair a panel or an area where panels join.
This procedure should be used only on secondary sur
faces of the vehicle (all surfaces below the level of the
top of the wheel openings). If repair of a panel requires
more than one-half the total panel area, the entire panel
should be refinished.
(1) Using mild detergent and water, wash complete
panel and rinse thoroughly.
(2) Clean repair area with wax and silicone re
mover, such as DuPont Prep-Sol, Ditzler Acryli-Clean,
3M General Purpose Adhesive Cleaner and Wax Re
mover, or equivalent.
(3) Remove loose paint and featheredge area with
sandpaper.
(4) Wash area to be painted.
(5) Mask area to be painted.
(6) If bare metal is showing through paint in repair
area, use following steps to prime area.
(a) Apply appropriate metal conditioner to bare
metal according to manufacturer's instructions.
(b) Mix primer following manufacturer's
instructions.
(c) Apply primer and allow to air dry.
(d) Remove masking and wet sand repair area.
(e) If scratches or pin holes appear in surface,
apply glazing putty according to the manufacturer's
instructions.
(f) After glazing putty dries, wet sand and
clean area. Apply final coat of primer and allow to air
dry.
(g) Wet sand and wash area.
(h) Clean repair area with wax and silicone
remover and wipe with tack rag.
(7) Wash complete area.
(8) Mask area to be painted.
(9) Mix acrylic enamel color using a paint shaker
and following manufacturer's mixing instructions.
(10) Adjust air pressure at air regulator to obtain 55
to 60 psi (379 to 414 kPa) at spray gun and spray test
panel. Adjust gun to obtain desired pattern and color
match.
(11) Apply one medium color coatto primedareaand
allow paint to set up for 25 minutes.
(12) Apply three or more medium color coats. Over
lap edges of each coat to produce tapered edge. Allow
each coat to flash completely.
(13) Spray one full wet color coat over entire repair
area. Overlap edges of previous coat.
(14) Empty gun and fill cup with enamel reducer.
Reduce air pressure at air regulator to obtain up to 20
psi (138 kPa) at spray gun.
(15) Spray blend-coat over edges of old and new
paint.
(16) Spray one or two medium coats over entire area.
(17) Remove all masking when paint has tacked up.
FINISHING METAL REPLACEMENT PARTS
Metal body service replacement panels or assemblies
are painted with a black factory primer. For proper
adhesion of acrylic enamel color coats in service, the
following refinish steps are necessary.
NOTE: If replacement aluminum, body parts require a
two part conversion coating beforecolorcoat is applied.
(1) Wash part with paint finish cleaning solvent,
such as DuPont Prep-Sol, Ditzler Acryli-Clean, or
equivalent
(2) Scuff sand part with 220 grade dry sandpaper.
Avoid cutting through and rewash part.
(3) Mix primer/sealer following manufacturer's
instructions.
(4) Apply primer/sealer and allowto air dry.
(5) Wet sand smooth and clean with DuPont Prep-
Sol, Ditzler Acryli-Clean, or equivalent cleaner.
(6) Apply acrylic enamel color coats asrequired.
(7) Clean inside of replacement panel and apply
anti-corrosive material as described above under Anti-
Corrosion Protection.
