c. Cadmium plated surfaces shall receive either a Type II<br />
supplementary chromate treatment or a Type III supplementary<br />
phosphate treatment per SAE-AMS-QQ-P-416<br />
(QQ-P-416) using procedures in <strong>TO</strong> 42C2-1-7.<br />
Bleached or clear chromate treatment of is not permissible.<br />

NOTE<br />
For DEPOT LEVEL maintenance, touch-up of small<br />
areas of zinc and/or cadmium plating may be accomplished<br />
by brush plating per MIL-STD-8651 using<br />
procedures in <strong>TO</strong> 42C2-1-7 in lieu of complete stripping<br />
and replating.<br />

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

e. Apply two coats of either MIL-PRF-85285 standard<br />
polyurethane coating or MIL-DTL-64159 waterborne<br />
CARC polyurethane coating to a DFT of 1.8 to 3.2 mils<br />
(0.0018 to 0.0032 inch) over the primer per procedures<br />
in Chapters 4, 5, and 6 of <strong>TO</strong> 1-1-8. The color and gloss<br />
shall match the existing coating system as specified in<br />
equipment system specific technical data or as otherwise<br />
directed by the equipment SPM.<br />
7.7.4.3 If surface is not exposed to view in its normal operating<br />
condition, except while under repair, use the same procedures<br />
specified in paragraph 7.7.4.2 step a, step b., and step c.,<br />
the NOTE under step c. and step d. Application of a topcoat<br />
per paragraph 7.7.4.2 step e is not required.<br />
7.7.4.4 Where only partial refinishing (touch-up) is required<br />
for a few small scratches, nicks, or spots where corrosion was<br />
removed on painted surfaces, the following procedure shall be<br />
used:<br />
a. Scuff sand and feather out painted edges and all corroded<br />
or scratched surfaces to be refinished per maintenance<br />
painting and touch-up procedures in Chapter 5 of<br />
<strong>TO</strong> 1-1-8.<br />
b. Clean the entire surface to be touched-up of all dust,<br />
dirt, oil, and grease by solvent wiping per procedures in<br />
Chapter 3 of <strong>TO</strong> 1-1-8 prior to priming. Apply one coat<br />
of the same primers specified in paragraph 7.7.4.2 step d<br />
to all surfaces to be touched-up (both those exposed and<br />
unexposed to direct view in normal operating conditions)<br />
using maintenance painting and touch-up procedures<br />
in Chapter 5 of <strong>TO</strong> 1-1-8.<br />
c. If surfaces are exposed to direct view in normal operating<br />
conditions, apply one coat of the same topcoats<br />
specified in paragraph 7.7.4.2 step e over the primer<br />
using maintenance painting and touch-up procedures in<br />
Chapter 5 of <strong>TO</strong> 1-1-8.<br />
