My primary concern with painting Subaru blue is matching the rear wing. Tamiya’s released TS-50 Mica Blue specifically for the Subaru WRC cars but that paint is for the styrene plastic parts, not polycarbonate.

The instructions call for PS-16 Metallic Blue but I think it ends up being too light or too green of a tint. I’ve used PS-59 Dark Metallic Blue with about a couple of coats, then finally backing it with silver. Let me look at my stash at home and I’ll know what I used. I tested the layers on spare polycarbonate to get the layers right. Use the wheel cutouts.
