So just for giggles........
I tested dollar store permanent markers brand ACADEMIX
and
here's a surprise.....
BLACK ink totally disappeared
BLUE ink faded away
but
RED and GREEN worked great!
Sound familiar?!?!?!
same thing happened with CASEMATE:

AND
since we were talking about drafting inks I looked around here and found
INDIA INK and FABRIC PAINT
The FABRIC PAINT DEFINITELY WORKS WELL. If I had to I would use FABRIC PAINT to protect
a copper board from acid.
The INDIA INK FLAKED AWAY
unreliably leaving missing copper traces.
