do it yaself... me and me bro did it on my ex's 182... just wet and dry from 400 to 2000grit, and finish with a decent metal polish. then spray the renault sport bit black, and sand back with a block for the polished lettering.
finally we got engine cover sprayed graphite, looked pretty good, i'm sure it hasn't aged very well now however, as the little car is abused and unloved the last i heard
