Worse case, it would be no different then using a metal boom.  It would
detune it slightly so you'd see some distortion of pattern or impedance
match issues.  If it was me, I would not loose sleep over it.  It might need
some tweaking.

We find in cellular at 850 MHz that we have to use paint without metal when
covering the fiberglass raydomes but painting the boom is nothing like that.
But unless you going to put this behind a painted wall it's not an issue big

Something just dawned on me.

I have been painting the wooden booms of my antenna

Does painting a boom affect it ?
