TO 1-1-700 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.

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. o 7-36 Change 4

Apply two coats of either MIL-PRF-85285 standard polyurethane coating or MIL-DTL-64159 waterborne CARC polyurethane coating to a DFT of 1.8 to 3.2 mils (0.0018 to 0.0032 inch) over the primer per procedures in Chapters 4, 5, and 6 of TO 1-1-8. The color and gloss shall match the existing coating system as specified in equipment system specific technical data or as otherwise directed by the equipment SPM. 7.7.10.2 If surface is not exposed to direct view in its normal operating condition, except while under repair, no further finish is required after plating. 7.7.10.3 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 7.7.10.1 step d to all surfaces exposed to direct view in normal operating conditions that require camouflage being touchedup 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 7.7.10.1 step e over the primer using maintenance painting and touch-up procedures in Chapter 5 of TO 1- 1-8. 7.7.10.4 If surface is not exposed to direct view in its normal operating position, except while under repair, no further finish is required after sanding and cleaning procedures in paragraph 7.7.10.3 step a and step b are accomplished if no base metal is revealed. Area shall be primed per paragraph 7.7.10.3 step b if base metal is revealed. 7.7.11 Lead on Copper, Copper Alloy, and Ferrous Base Metals. When complete refinishing is required due to extensive corrosion or loss of plating, disassemble the equipment and/or structure as far as practical; and proceed as follows: 7.7.11.1 Lead plating is used primarily as an anti galling agent in bearing applications and as an aid for soldering. It will not be exposed to direct view in its normal operating condition and it does not require painting after application. Perform replating operations as follows: 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, lightly sand areas where corrosion is noted to remove corrosion products of the plating and clean the residue off per procedures in Chapters 3 and 5 of TO 1-1-691. If base metal corrosion is noted, return the equipment to the prime depot for rework. b. Lead plate copper or copper alloys per MIL-L-13808, Type II, Class 1 to a minimum thickness of 1.0 mils (0.0010 inch) using procedures in TO 42C2-1-7. c. Lead plate ferrous metals after plating with a copper strike plating per MIL-L-13808, Type I, Class 1 to a minimum thickness of 0.015 mils (0.000015 inch) for the copper and a minimum thickness of 1.0 mils (0.0010 inch) for the lead. d. No further finish is necessary. 7.8 MIL-C-10578 METAL CONDITIONER. MIL-C-10578, COMPOUND, CORROSION REMOVING AND METAL CONDITIONING 20 MIL-C-10578, Type I (wash off) and Type II (wipe off) corrosion removers and metal conditioners provide excellent surface preparations to promote good paint system adhesion on metals such as zinc galvanize and plating, tin, nickel, and chromium as well as providing minor corrosion protection for these metals in an unpainted condition. Preparation and use of these materials as directed elsewhere in this chapter of this manual shall be per the instructions in Chapter 5 of TO 1-1- 691, and all precautions and warning listed therein shall be followed. NOTE MIL-C-10578, Type I and II materials may be obtained through the normal Air Force supply system under NSNs listed in Appendix A of TO 1-1-691. 7-37
