right my wheels are getting refurbed this week and i wanna keep them clean obviously,but how do i stop them getting dirty from brake dust? is there a spray or something i can spray on the alloy that stops dust from sticking to them?i remember something ages ago like a clear disc you put on the inside of the alloy to stop dust coming thru the alloy? do these exist? and would it affect air not getting to the disc and not cooling the disc/pads??? any help appreciated
