Evening.................
I've got a set of VR6 BBS's that I want to refurb, but I'm looking for a tad of advice please

I'm painting them metallic black, I know how to do all that, no probs there, but I thought I might try a 'Polished Rim'

Obviously the wheels are standard silver at the moment, with no kerbing, filling to worry about. So, when I've rubbed them all down, I want the polished (mirror like) lip, which I will mask off before painting.
How do I get the mirror finish on the lip?
Do I spray the entire wheel with undercoat, colour, lacquer & then rub the lip back?
Do I need to lacquer the polished lip when/if I get it to that stage?
Any help greatly appreciated.

PS if anyone has a Dragon Green mk3 with this type of wheel and finish, could you stick a pic up please
