4.13 Finish and pretreatment (see 3.13).
a.
Where technical drawings and the equipment specification specify olive drab finish for piece parts,
subassemblies, and assemblies, these shall not be finished with the lusterless forest green paint
conforming to film designation "V" in MIL-DTL-14072 "V", but shall be finished with the Chemical Agent
Resistant Coating (CARC).
b.
Requirements are as follows:

.0006 to .0009 inch (0.015 to 0.022 mm).
(c)
In order to paint the Lexan Base with CARC, a primer is required. The USA Belvoir Research
and Development Center recommends using primer MIL-DTL-53022. The color of the part as
molded (prior to painting) shall be as close as possible to Green 383 by pre-mixing the material
with color pigment.
(d)
Final finish coating shall be type II Green 383. Final finish is applied at a minimum of .0018 inch
(0.045 mm) dry in two coats.
(e)
Antennas: Finish coat on signal radiating or receiving elements where specified on drawings,
must be type II, Green 383.
(2) Color: Color of external surfaces shall be type II Green 383.
c.
The equipment shall be marked with the word "CARC" in close proximity to the ID nameplate or N.S.N.,
