Hi Carl,
From my experience, there are a lot of those out there that use a touch-up pen that is commercially available:

What this is, is green colored acrylic coating. You should be able to remove it with IPA if it is...

Subject: [TN] How can I remove solder mask?
I have a PC board that somebody has repaired, and then painted something that looks like the standard green soldermask to cover the repair. There is still a short circuit under the painted area. I'd like to analyze the repair, but I don't want to just scrape off the covering with a knife blade. Is there an easily available solvent that can be used to remove soldermask?
Thanks,
Carl
p.s. I check the archives, and was unable to get any results with the search function. It seems to be broken . . .
