Okay I’ll get a few of those. I thought Sharpie could handle it but apparently not.
I also purchased some dry-transfer PCB stuff.. has traces, pads, etc.. could use some of that.

Staedtler Lumocolor Red works well and the FeCI does not affect it at all.
Bought on E-Bay four colors 10.00 or so USD. Have only tried red so far but it works for touch up real well.
