Order you some Mack pinstriping brushes and some one shot paint. Just sit down and play with it. Not hard, very rewarding. I have painted 3 sets now. Never thought that I could do a single one.

Tried the method of painting the entire plate the color of the numbers with epoxy paint, then overcoating with the background color with a laquer based paint, then wiping the background color from the numbers. You know what I ended up with? A mess!
