PROBLEM TO BE SOLVED: To allow paint to be uniformly coated in a specified film thickness without causing coating unevenness and without requiring skills.SOLUTION: A tip portion of a paint-coating sponge 14 is contacted with an upper end of a glass surface 2A of a window glass 2, an end of a lower pressing piece 28 is contacted with the glass surface 2A, a winch 18 is driven and a wire 34 is wound up at constant speed using the winch 18. Subsequently, in accordance with the winding-up of the wire 34 using the winch 18, an operator descends a frame 16 while keeping a horizontal state of the frame 16 and a parallel state thereof to the glass surface 2A. While descending the frame, the operator descends the frame 16 visually recognizing a mark portion 2204 so that the mark portion 2204 is positioned between an upper edge 2206A and a lower edge 2206B of a window portion 2206. This causes speed required for lowering the paint-coating sponge 14 to be within a predetermined value range so that speed required for moving the paint-coating sponge 14 along the glass surface 2A can be uniformly kept within a specified range without requiring skills. |
