Luminous paints (Glow in the dark stuff)

I have an experiment in mind..but I was wondering if anybody here would know much about "glow in the dark" paint?
I'm considering sanding off the stardard orange on the back of the fto needles..and then replacing them with some glowy stuff..
Is water based stuff any good?
Do I go for metal stuff??
