Bill's comments have set me off into thinking something else, another
possible application of conductive epoxy paint.
Here is my thoyghts:
We may realize a stelth dipole antenna on wing surface. If L/R wing pannel
can be insulated electrically, install one each electrical terminals at wing
roots, finish paint the wing pannels with conductive paint all surface to a
CF composite wing (don't do it if wing is not made of CF), paint in one
complete surface including the electrical terminal per wing half.
Why it works? why paint all surface?
Radio frequency current is known to run on surface of conductors at
operating frequency at 10MHz and higher. This is called the Skin Effect. By
which the core metal becomes a dummy conductor metal section that can be
"carved" out without significant electrical performance reduction. Once the
metal rod is hollowed, any carbon composite construct (not in electrical
contact to the conductor) in the core will not induce/carry RF current and
therefore do not dissipate energy. A conductive coat on a CF composite wing
surface can "hide" the RF hungry carbon composite under the skin current.
