Fastandfurious, I just colored in the dots with a red Sharpie marker on mine. You have to be very careful clear coating over marker, or it will just make a mess, but if you lay several light misting coats before you lay any thicker ones, you should be ok.
However, I was just using what I had laying around. Ideally if you were painting with enamel, then you would want a little jar of model paint, like Testors or Tamiya. If you're painting with acrylic laquer, like me, then you need a little jar of touch up paint from the automotive store. (Pep Boys, Autozone, etc.) Candy Red should come out transparent, and you'd just dab it on with a fine tip paint brush, that you can find at a craft or art supply store.
I painted mine silver from the outside, because I had already used silver as a base coat, but in
Cabo Wabo's thread for his S2000 he painted his silver from the inside, and that has a nice realistic effect. I'll be using that on my next project.
