Choice of Paint for use over Copper foil Antennas

Quick question regarding the copper foil antennas....

I have a Vari-Eze and have successfully used Jim Weir's RST copper foil
antennas for years in my canard and winglet. It is time to repaint the
aircraft and I was about to decide on PPG DP epoxy primer (white) and an
acrylic urethane topcoat (white) made by Spies Hecker (German company)....
Then I recalled reading one of RST's newsletters about the foil antennas
where it was reported there had been a paint incompatibility problem on one
occasion....(Antenna didn't work possibly because of high metal content in
the paint?) What type paint caused the problem and have you any newer data
that would confirm (or not) that I am OK using the paint combination I
mention above?

thanks

I be damned if I can find any information. Twenty years ago, some dude wrote me
that his antennas were totally wiped out because of "some German paint". I
couldn't get any more information from him, nor have I had any other
confirmations of this phenomenon.

My wild ass guess is that the "dude" screwed up installing the antennas as was
more willing to attribute the foulup to "paint" rather than "craniorectal
insertion".
