>>7161681>>7161697>muh gunmetal frameyou niggers need to keep the scale in mind
even if the object is made of "gunmetal" it doesn't mean the metal is left bare:
handguns - not painted
artillery pieces - always painted
you can try to make a case that space based mechs don't need paint (but then why is the armor painted gay pink?) but ground based mech would never ever have bare metal frame
