Thats right, the head in the play field.
Mine has lots of re-paint and runs on it, looks like someone emptied a full can on it at some point prior to it landing with me.
I could sand it down and spray but its in a sorry state so thought i'd try my luck if anyone had unbutchered one to refirb.
The problem I see with spraying, is getting the blue plastic back in after paining.
Chrome spray paints don't like being touched, and you would need to handle it a fair bit to put back together.
I know the chrome sprays are not the best, but was R2 ever chrome anyhow?
