On that one, I'd repaint it. Those metallic colors are extremely difficult to match, since they're a candy-color over a specific color primer. I've had some good results though on one, but it took forever. The colors can't be matched with just using a similar color, you need to mix gold and silver metallic paint (Testors enamel paint set) together as your base, then add in the blue until you reach the correct shade. Note that it will darker up a bit from what you mix, so it's a LOT of trial-and-error. Even with an exact match for the final paint color, you'll end up with a different sheen to the touched-up spots, and your results will probably look like a leopard in the sun, from that many spots needing paint. Your best bet is a repaint, you'll be much happier.
