I'll assess each wheel on its own merit, but it seems to me that they will just need to be sanded back a little and painted as they are. I dont have a problem with you just getting them off ans me collecting them and getting them done. You can collect them almost anytime as far as I'm concerned m8.
Sorry, not been in touch but the weather has been so poor every weekend (and it's now the rugby season, so Saturday's are difficult) I just haven't had time to take the wheels off!!
As money is a little tight until the car is sold, would it be a problem is I just take them off the car and bring them to you, when I can?
As for blasting & polishing, I think I'll stcik with silver painted but not the polished lip, it's not really big enough to bother. I'm led completey by you on blasting - if it's necessary/better, fine, if not, don't.
