The inside faces of the 20" FE wheels were factory shot blasted by Audi, not painted, and then the front faces were diamond cut -any refurb will not be able to replicate the shot blast effect fully, but may come close if it, particularly if they can create a colour which is close to "white silver" effect on the inside edges.

Any diamond cut (original or refurb...) is more prone to problems than a normal finish, but this can be reduced by protection with a further aftermarket coating, such as Metalmate.

Hope this helps.

I'll be honest I'm really surprised they were diamond cut from the factory. I've been looking for a photo of a D2 FE when they were new to have a look.

I've got a brand new unused spare one from the factory - and it is diamond cut as the others have intimated. I'll try and get pics of it next time I'm at my workshops +++

That would be great, I'd really like to see the original finish. Thanks.

Backs of mine from Lepsons were a white'ish paint / powdercoat finish, I very much doubt the factory finish was bare uncoated shot blasted aluminium.

Didn't say bare uncoated….
