Is that factory finish?!? Or have you had them painted previously?
They look like they've been painted by someone who didn't really know what they were doing.
IMO you should take this opportunity to have them powder coated in the finish of your choosing. Plenty of choice, and more durable than paint.
Powder coating will look great, but conventional painting will be easier to fix at home should you curb the rims at some point...
Could you please upload some pictures of your audi a3 alloys that had been powdered coated as I have the exact same wheels and wanted to know what colour would go well,I ended going powder coating route, very happy and it looks really nice,
