The grey coating prevents corrosion and is impervious to organic solvents; it does not need to be removed before rotor installation. The coating is removed by the action of the pads contacting the rotor; no rotor damage will occur nor will the pads become clogged by this coating.

M-B switched to this coating several years ago and released an S.I. stating that the coating was not to be removed.
