Nick-
Would you consider a laser scored ice rink? We have done this for track diagrams. Basically, the lines are all engraved on the back/bottom. You mask the entire surface and then knife along the score line to remove the tape for the first color. You paint the first color and mask it out. Then you knife each suceeeding color. When all the lines are painted, you would then paint white. Give me a call to chat it through.
