(3) Battery compartments. Battery compartments
should be neutralized, surface stripped, and cleaned
prior to painting.
(a) Neutralization of acid electrolyte. Exercise
care to prevent acid from spreading to adjacent areas.
Wash areas affected by battery acid with 20 percent
solution of sodium bicarbonate, Federal Specification O-
S-576, in water. Neutralization is completed when
bubbling ceases. After neutralization, remove all traces
of sodium bicarbonate solution with generous quantities
of water to prevent corrosion.
(b) Neutralization of alkaline electrolyte. Exercise
caution to prevent acid from spreading to adjacent
areas. Wash areas affected by electrolyte with 3
percent solution of boric acid in water. Neutralization is
completed when bubbling ceases. After neutralization,
remove all traces of boric acid with generous quantities
(c) Treatment after neutralization. Treat affected
area by swabbing with 5 percent solution of chromic
acid, Federal Specification O-C-303, or 5 percent of
potassium dichromate, Federal Specification O-P-559.
Follow by flushing with water, thorough drying and
mechanical stripping of any areas that may require
stripping. Thoroughly clean and dry the affected area in
accordance with TM 55-1500-333-24.
(d) Painting. After neutralization, stripping and
cleaning, apply the following paint system:
1 Apply two coats of epoxy polyamide primer,
MIL-P-23377, type 1 or MIL-P-85582.
2 Apply over these coats one coat of primer
coating epoxy, MIL-P-52192.
MIL-P-23377 is yellow, MIL-P-85582 is
green and MIL-P-52192 is red. When
wear, scratching or topcoat damage
occurs, yellow, green, or red primer
undercoats will expose, indicating that
repainting is necessary. This is essential
to protect the substrate structures.
3 Apply a topcoat of Lacquer, Acid Resistant for
Aluminum, Federal Specification TT-L-54, or Varnish,
Asphalt, Federal Specification TT-V-51, for other than
magnesium substrates. MIL-R-81294
