CPC REQUIREMENTS.
NOTE
Do not apply thermal spray pure zinc, 85/15% zinc/
aluminum or pure aluminum to stainless steel muffler
components.
3.26.3.1 Remove corrosion with abrasive mat, A-A-58054
and MIL-PRF-680, Type II or III, CID A-A-59601 or MIL-
PRF-32295, Type II, wipe off residue and allow to air dry.
Solvent will cause softening and deterioration of rubber
gaskets, seals, and insulation.
3.26.3.2 Clean electrical contacts with MIL-PRF-29608,
Type I, Electrical Contact Cleaner.
3.26.3.3 Apply a thin layer of CPC, MIL-L-87177, Grade B,
to the contacts.
3.26.4 Internal Electrical Components: Circuit Breakers,
Relays, etc. Instructions for removing and cleaning internal
electrical components are as follows:
Figure 3-4. Corrosion Under Data Plate
3.26.1 Sealing of Addressograph or Dash-A Plates.
Whenever an Addressograph or Dash-A-Plate is used in lieu
of die cut vinyl markings or stencils as data plates, they should
be installed wet with corrosion inhibiting sealant, MIL-PRF-
81733. The requirement for wet installation also includes the
fasteners used for installation. Using the sealant will prevent
corrosion from occurring between the data plate and SE.
3.26.2 Electrical Hardware and Terminals.
Do not remove thin plating on electrical components.
Always use the mildest method of corrosion removal.
3.26.4.1 Remove heavy corrosion by rubbing contact surfaces
with an abrasive typewriter eraser. Remove light to
medium corrosion by rubbing contact surface with ruby red
eraser.
3.26.4.2 Clean contacts with MIL-PRF-29608, Electrical
Contact Cleaner, Type 1, Class C. Clean relay or circuit
breaker assembly with acid brush, A-A-289. Remove foreign
matter with a soft brush.
NOTE
Clean corrosion on terminal studs with a wire brush
or terminal stud-cleaning tool.
3.26.2.1 For cables and terminal posts, brush on a light coat
of petrolatum, VV-P-236 Grease.

Type II (Lead and Chromate Free Epoxy Primer) and one coat
of MIL-PRF-85285 applied to a dry film thickness of 1.6 to
2.4 mils.
3.26.3 Light Assemblies. Instructions for cleaning the light
assemblies are as follows:
• Do not apply CPC MIL-C-81309 to printed circuit
boards. Contact points must be clean for CPC to
function properly.
• Care must be taken to avoid removing thin plating.
3.26.4.3 Apply a thin coat of CPC MIL-L-87177, Grade B,
to relays and contacts
3.26.5 Electrical Connectors. Remove light corrosion with
