would anyone use black light ink for marking things?

there are definately advantages, black light paint shines back even when the booth is dark. Also, it’s invisible so you can’t see it in normal light. Write down your own control labels right over top of the regular control labels and you’re set, and the original labels are still there for resale (until the dude takes it to a club and the black light makes it impossible for him or her to read the original words).
I personally use it for my black arcade buttons, but they would work for the korg padkontrol as well, and any other controller that doesn’t already have backlit buttons. Granted, just marking them doesn’t show whether or not they’re engaged, but it does help the accuracy methinks.
the downside is that you are best off bringing your own black light, but there are led blacklight strips for cheap and they don’t look like you brought a little desk lamp in to dj in your office.
Also, I’m fascinated by using a tablet for playing a cool synth, and black light ink would be perfect for drawing boundaries on a thing like that. Check this out:
Use a tuner and find the pitch centers and mark them with the ink. That way you could make big accurate leaps without worrying about over shooting or anything.
What other things could you use the black light for? There must be some good ideas out there.
