>>10049666This. OP sounds like they've clearly never customized before. If you have to ask about paint and such, don't bother trying to fix this yourself. It's not as simply as slapping paint on it. You need a fine brush, thin your paints correctly, and either color match SPOT ON or re-paint the entirety of the blue parts of the head so its consistent. This after filling in the holes, sanding with finer and finer grit paper to have it as smooth as the head, etc. I say find a customizer who can do it for you instead of spending $50+ in materials between putty, sand papers, paints, brush, spray sealer, etc.
