7.7.9.2 Where only partial refinishing (touch-up) is required
for a few small scratches, nicks, or spots where corrosion was
removed on painted surfaces, the following procedure shall be
used:
a. Scuff sand and feather out painted edges and all corroded
or scratched surfaces to be refinished per maintenance
painting and touch-up procedures in Chapter 5 of
TO 1-1-8.
b. Clean the entire surface to be touched-up of all dust,
dirt, oil, and grease by solvent wiping per procedures in
Chapter 3 of TO 1-1-8 prior to priming. Apply one coat
of the same primers specified in paragraph 7.7.9.1 step b
to all surfaces exposed to direct view in normal operating
conditions that require camouflage being touched-up
using maintenance painting and touch-up procedures in
Chapter 5 of TO 1-1-8.
c. Apply one coat of the same topcoats specified in paragraph
7.7.9.1 step c over the primer using maintenance
painting and touch-up procedures in Chapter 5 of TO 1-
1-8.
7.7.10 Bright Chromium on Ferrous, Copper, and Copper
Alloy Base Metals. When complete refinishing is
required due to extensive corrosion or loss of film adhesion,
disassemble the equipment and/or structure as far as practical.
Remove the defective paint system per procedures in Chapter
2 of TO 1-1-8.
7.7.10.1 . If surface, when reassembled in its normal operating
position, will be exposed to direct view and camouflage is
required, use the following procedure:
a. For DEPOT LEVEL maintenance only, strip old plating
from equipment or part to the base metal per procedures
in TO 42C2-1-7. For FIELD LEVEL maintenance and
when it is impractical to strip the plating due to size,
shape, or connection to other parts, lightly sand areas
where corrosion is noted to remove corrosion products
of the plating as well as the base metal per procedures in
Chapter 5 of TO 1-1-691.
b. For DEPOT LEVEL maintenance only, reapply copper
plating on ferrous base metals per SAE AMS 2418
(MIL-C-14538); nickel plating on both copper plated
ferrous base metals and copper and copper alloy base
metals per SAE AMS-QQ-N-290 (QQ-N-290); and
chromium plating on both copper/nickel plated ferrous
base metals and nickel plated copper and copper alloy
base metals per SAE AMS-QQ-C-320 (QQ-C-320),
Class 2 using procedures in TO 42C2-1-7.
NOTE
For DEPOT LEVEL maintenance, touch-up of small
areas of copper/nickel/chromium plating may be accomplished
by brush plating per MIL-STD-8651 using
procedures in TO 42C2-1-7 in lieu of complete
stripping and replating.
(1) Copper plating on ferrous base metals shall have a
minimum thickness of 0.65 mils (0.00065 inch).
(2) Nickel plating on copper plated ferrous base metals
and copper and copper alloy base metals shall have a
minimum thickness of 0.6 mils (0.0006 inch).
(3) Chromium plating on copper/nickel plated ferrous
base metals and nickel plated copper and copper
alloy base metals shall have a minimum thickness of
0.3 mils (0.0003 inch).
NOTE
Chromium plated surfaces do not require painting except
when they are exposed to view and camouflage
is required to restrict the visual signature of the
equipment.
c. Treat the plated metal surfaces with the metal conditioner
described in paragraph 7.8 of this manual.

d. Prime the treated plated surfaces with one coat of MIL-
PRF-23377, Type I, Class C or MIL-PRF-85582, Type
I, Class C2 epoxy primers to a DFT of 0.6 to 0.9 mils
(0.0006 to 0.0009 inch) or MIL-DTL-53022 or MIL-P-
53030 epoxy primers to a DFT of 0.9 to 1.1 mils
(0.0009 to 0.0011 inch), as applicable, from the equipment
system specific technical data. Application shall
be per procedures in Chapters 4, 5, and 6 of TO 1-1-8.
