Try users NHN or N8 for wheel refurb. :) x
I have, had mine done gunmetal by them. They are ok, I had trouble with one wheel as the paint wasn't right then they had another go and another go until I eventually said start again as all they where doing was spraying over it. For the price they are good but it depends how much more it would be for NHN or N8 to do them if its £50 for example, go to them.
