What do you use to wipe it in with and wipe it out with so it wont scratch the wheel.[urlhttp://www.formymercedes.com/wheelcare.asp[/url]
Take your pick
I got the metal protector and a metal polish and it works for me.
If your wheel is clean, the metal polish is not necessary (unless you want to clean the inside, or want to clean brake dust stains off). The metal protector forms an invisible resin which seems to resist brake dust much better than normal wax/polish, which burns off far too quickly due to the heat from the brakes.What do you use to wipe it in with and wipe it out with so it wont scratch the wheel.
