moisture and fungus growth by an overall treatment with varnish conforming to MIL-V-173 or a
varnish having 1 percent of copper-8-quinolinolate or 6 percent galicylanilide (by weight) based
on the nonvolatile content of the varnish, with the following exceptions:
a. Components or circuit elements which are inherently fungus and moisture resistant or
which are hermetically sealed need not be treated.
b. Components or circuit elements whose functions will be adversely affected by the
varnish coating shall not be treated.
When used, varnish shall be applied by spray, brush, or a combination of both to give a
minimum dry-film thickness of 0.001 inch to component and element surfaces previously
cleaned and prepared so that the surfaces are free from all foreign matter which would interfere
with the adherence or functioning of the varnish.
