I've got a set of BBS CHR's and currently they're in black with slight curbing rash and basically I'm after getting that fixed aswel as getting them made silver and I was wanting to know where you guys would recommend getting this done and what method you would go of painting them. The black ones are what I have currently, and the other is what I want them to look like and I'm happy to take them anywhere between Taupo and Auckland
