Prof.,
Using the AAA as a base coat might work, but it kind of overrides the reason for using AAA instead of a "regular" silver paint. May I suggest testing your idea first by using another, cheaper/more available silver paint (probably mica based:raped

in place of the AAA.
I forget, are you rolling or spraying your screen? If rolling, others have had problems using such high concentrations of metallic paint - they get roller marks.
And definitely keep us up to date on your project, we're rootin' for ya!
