You guys are probably right and it is all painted. The only thing with painting the whole figure is why not buy a removable limbs beater and paint it instead of casting a whole figure. Is it that cheap to make a mold and then cast these out instead of buying the beaters around?
Notice for a casting how much detail it was able to capture with the little wires and chest circles and even the coo, but you can tell on the feet and left hand how jacked up it got in those areas.
