Rob,
There is one color shifting paint(PPG?)that changes color 8 times! The bad part about these paints, is that inevitably, one of the colors isn't too pretty(ugly!)! They look good to a point, then you see that "mergatroid" color, and it ruins the entire look. It does for me anyway. This stuff isn't cheap either! Have you priced it? OUTRAGEOUSLY high!
