Yup!
I bought a set in pretty scratched condition i.e. probably half the wheel curbed on each wheel!
Went down Halfords and got the alloy repair kit they do (£25) and spent a couple of summer days doing them up. Basically you rub them down using emry paper, fill all the groves and chips in with super glue filler, rub it down again and then spray them. All 4 of mine turned out luvvly, only one is a bity cack now cos it was the first wheel i done and i didnt finish it properly.
HTH
BTW this was on phase 2 16v alloys so anything with more spokes might be a bit more difficult - ur looking at around £40 a wheel for a full refurb.
