A good while ago Now I did come across a range of glow in the dark paints that could be used for fabric though can’t remember if it stated they’d be OK for rubber.
The line included florescent orange which gave the brightest glow all night, next up where the florescent yellows and greens which where almost as bright and long lasting. Blue which gave a softer glow and only lasted part of the evening round 5 hours or so. Red which gave a dull glow for a couple of hours in almost total darkness and purple that gave a very soft glow for an hour or to around twilight conditions.
The glow in the dark powder paints that you often come across might be an idea as they’ve been commonly used on rubber toys for a good while now. I think they usually only give that blue green glow. They would still work under UV light although not sure if the Uvlight it’s self would be good for pleo skin.
Hope this helps
