Pikced up some GitD Acrylic paint at a Jo-Anns fabrics near me; tried it out on a white Pakari, 03 Lewa Nuva sword, and a Mahritoran dagger, and it's looking pretty good. Goes on transparent, but it needs about 4 coats in order for it to actually glow. First coat, it seems to all fall on the edges, which is a neat effect if you just leave it that way. I am planning to do a whole set of armor this way, the Ghost Walker armaments.

Also, since my Faerie sword has the Druidic crescent moon motif on it, I'm planning on painting Oghamic runes onto the scabbard, as sort of a mystic thing. I think it'll look cool.
