Has anyone any experience using pens with ink that is invisible under
normal light, but shows up under UV for identifying areas of PCB's
needing rework? This would remove the need to place and remove stickers
on the components and PCB and be invisible to the end customer. 

Various pens are on the market for to let you mark your property, but
there is no information that I've been able to find for their use on
PCB's. Ideally I would want one that has been shown to be safe for use
on electronics and have low ionic contamination.
