Okay, one of the essential parts to pay attention to when working on something like the metal slug gashapon set is the figures. You can paint up the vehicles all nice and all but the figures also need that sort of attention.
That being said, it's pretty hard to paint them up right when they're one solid piece of PVC (or rather several parts firmly held together by glue).
If I wanted to paint the figures entirely, meaning ALL the little crevices and gaps, I can't accomplish that by just painting them as-is, or rather you can but it'll be way to difficult and nerve-wracking for your hands.
What could you do?
