Mikey,
There are some paint companies that make paints for RC car bodies, (made for plastic paints) and they have the following glow in the dark colors:
Blue
Purple
Red
Orange
Yellow
Green
light blue
light green
they also have glow in black light colors that look clear on the piece but glow in the black light (so you can paint them over a regular painted part so when black light isn't on it you just see the under color). Now these apints are not cheap but they are fantastic! Ihave the whole set of both and it only just now occurred to me to start using them on figures!! doh!

I have glow in the dark paint and its like a lemon color. What paint did you use??? Whats the secret???
It looks good! I've thought of doing this one, but there a lot I think of doing!
Great work!

Your silver is amazing! Your paint is very clean although I think the pants could use a wash or a two tone drybrush but I'm far from qualified to nit pick. Once again, the silver is simply fantastic and I like the color combo on the costume. Paint lines are really clean too!

I can't wait to see this guy screw some crud up with the green lanterns. Between him and the Sinestro Corps, the future is bleak for the emerald knights. Excellent custom, I want to make myself one of these in a bad way. Good job.
