E coating or electrostatic coating is a surface protectant that is sprayed on the part to prevent rusting/corrosion etc. It is also applied for appearance purposes. There is no need to remove it . If you do remove the coating the wear surface of the rotor that the pads rub on will rust. It does not affect braking performance at all if left on. FED 387
