While I don't have any Paul brakes, over Life I've had plenty of aluminum 
parts that were of a natural, untreated finish. You can polish them all you 
like, but it doesn't last every long until they require more polishing. The 
polishing is an attempt to seal the exterior, to create a "buffer" from the 
elements, so to speak. It's high maintenance for sure as it's only 
temporary.  The durable hard anodizing manufacturers use is a chemical 
process and as long they're not exposed to excessive corrosive elements the 
finish remains indefinitely. Once that finish is removed, there's no going 
back, they are back to their natural untreated state. A sure way to tell 
the finish of any aluminum part is to rub it with a clean rag or even your 
hands as it will leave that telltale gray residue. 

As far as I'm concerned if a part is finished black, or anodized a dull 
silver, I leave it alone, or don't buy it in the first place if I can't 
live it as purchased. There can be a few exceptions, notably if it's 
something tiny. Surely though, I see black and silver parts as 
complimentary rather than conflicting.
