very few people will refurb a machined finnish
why don't you look out on ebay for a single genuine one, seen them go for around £100 recently
a refurb would probably cost at least that much anyway by the time you get the tyre off and remounted
Lepsons repaired a couple of EOS Chicago wheels with same finish for us and did an unbelievable job on them,i couldn't believe it when they came back.
