Find paint that is similar to the pearl or metallic finish used. I doubt you will find an exact match. You might have to buy 2-4 colors to mix and match what is actually used. I don't recommend buying hobby paints, they are just too goppy. Look into airbrush ready paints. They are thinner, easier to apply and go on even. Well, most of them do. I would recommend Garage Kit Colors or Faskolor. Faskolor is mainly used in painting RC lexan bodies. But I use it quite a bit and I like it. Garage Kit Colors has a pearl line that might prove your best option. There are people on here with way more experience than me though.
