As my clubman GRP bonnet always flaps around and wobbles at high speed I am looking into an aluminum bonnet.
So it got me thinking that a brushed alloy bonnet would look a bit nifty- but how do rolls royce (as they're the only cars I can think of that do that) "brush" their bonnets and how do they stop them from oxidizing?
Any ideas welcome, even if its a "would look *rubbish*!" lol
