Brushed Aluminum Wheel Centers

[Neil B]

I've got a set of 1-piece billet aluminum wheels that are fully polished. I like the wheels, but I want to reduce the bling and achieve a more purposeful look. Powdercoating is expensive because they would have to heat tape the wheel to keep the polished lip. I don't want to paint the centers because I want a more durable finish. What's the best way to create a brushed aluminum finish on the wheel center while leaving the outer rim polished? Can I Scotchbrite or wetsand the spokes to achieve this look?

Thanks. -Neil
