The reason there are conflicting answers is because there are
conflicting results. Some have painted their plane with a metallic
paint and found that the radios worked fine. The original builder
of my 235 stripped off a layer of paint after discovering that the
radios no longer worked. The failed assumption is that all
metallic paints are the same. Instead there are conductive and
non-conductive metallic paints. There are also metallic paints
that become conductive after a few electrostatic discharges.

So if you want to paint your airframe a metallic color, test the
paint that you are considering. Or use what Fred used.

One Lancair with metallic paint didn't melt in the sun. Therefore all Lancairs
with metallic paint are safe... Same logical fallacy.

Fred is quite right to suggest that piloting is more important than paint.
