A fastened member such as a hinge which is a metal fastened member to be fastened with at least one fastener to at least one attachment surface of at least one target object such as a construction machine to which the fastened member is to be attached, the at least one target object containing steel, the fastened member including at least one contact surface to make contact with the at least one attachment surface, the at least one contact surface at least partially including at least one exposure portion where material having a higher ionization tendency than steel is exposed, wherein a portion of the fastened member that is other than the at least one contact surface is coated with a coating.

A bannister spindle painting cover having a head with a fixed dimension notch is formed therein, the notch including a first inside edge and a second inside edge with a third inside edge extending therebetween. The third inside edge is normal to the first and second inside edges, the first inside edge and said second inside edge being parallel to one another near the third inside edge. The cover may have a thickness of no greater than . The head may be planar. In use, the cover may be positioned around the square portion of a bannister spindle such that three sides of the spindle are in nominal contact with the notch to facilitate painting of the spindle while keeping adjacent stair treads paint free. The cover may be withdrawn and repositioned at least 90 degrees on the spindle as needed for painting multiple sides of the spindle.

A coating apparatus includes a jig supporting a guide vane equipped with a metal sheath covering a leading edge portion; a nozzle spraying paint onto a vane body; a robot moving the nozzle; and a control unit controlling a spraying operation of the nozzle and robot. The jig includes a movable covering body adapted separably covering the metal sheath and covering an exposed portion of adhesive between a lateral edge portion of the metal sheath and the vane surface of the vane body, and a covering body drive unit moving the movable covering body between a state in which the movable covering body covers the metal sheath and a state in which the movable covering body is separated from the metal sheath while covering the metal sheath. The control unit performs control to make transition from a sheath cladding coating mode to a finish coating mode.

An aircraft structure component for laminar flow, the aircraft structure component having an outer skin with an aerodynamic surface, wherein the aerodynamic surface has a leading edge portion and a downstream portion adjacently downstream from the leading edge portion, and wherein the downstream portion of the aerodynamic surface includes a paint layer that is not present in the leading edge portion, so that an edge line is formed between the leading edge portion and the downstream portion by the beginning paint layer. An object, to provide an aircraft structure component that allows for a reduced aerodynamic drag, is achieved in that the edge line has a ramp-shaped cross section, wherein the thickness of the paint layer increases from a starting point over a predetermined ramp length to a saturation point where the full thickness of the paint layer is reached.

A paint template system includes a vertical support surface and a horizontal support surface intersecting the vertical support surface. A baseboard is coupled to the vertical support surface. The baseboard is coextensive with an intersection between the vertical support surface and the horizontal support surface. A template is provided and the template is selectively positioned on the horizontal support surface. Thus, the template inhibits paint from spilling on the horizontal support surface when the vertical support surface is painted. The template is selectively positioned to cover the baseboard. Thus, the template inhibits the paint from contacting the baseboard when the vertical support surface is painted.
