I have a 2011 WRX with the stock dark grey wheels (is that paint or powder-coat)?
Can I use Meguiar's All Wheel cleaner on those, or do I need one of their specific wheel cleaners? I used the all wheel cleaner once and the next day it looked like there was just a bit of white residue left over. Is that normal?
Finally, after washing the wheels, I noticed the next day there was a very thin layer of rust on the rotors. It came off after driving and braking for a little bit, but is that normal and ok too?
Thanks for all the help!
