A method of applying a protective layer forming material by rolling a roller mounted on a roller mechanism over a surface of a workpiece, using a trainable coating apparatus disposed near a conveying line for conveying the workpiece, and applying the protective layer forming material in a liquid form to the surface of the workpiece, which is supplied to said roller and which will act as a peelable protective layer after being dried, said method comprising the steps of:

  • when said roller is rolled over a curved area of said workpiece, rolling said roller at a speed lower than when the roller is rolled over a substantially flat area of the workpiece; and

    when said roller is rolled over an area having a groove of said workpiece, orienting an axis of said roller substantially parallel to a direction in which said groove extends, moving said roller in a direction substantially perpendicular to the direction in which said groove extends, pressing said roller against said groove, and rolling said roller at a speed lower than when the roller is rolled over a substantially flat area of the workpiece.
