I like Flourescent. I get it at HomeDepot.(like $4) It comes in Blue,Green,Pink,orange and yellow.
Best way to paint it is to paint the part FLAT WHITE first. Than the cloor over the top. It goes on much more even...
Also I use the Metalics (I like the Black best) and put clear on it after its dry. It sparkles when light hits it.(also HomeDepot, Lowes or your local hardware store)
