PURPOSE: To color a surface of an FRP product with a clear boundary line by a method wherein a mold surface is partitioned with a boundary and one side thereof is covered with a sheet, the exposed surface is coated with a gel coat having a pigment A mixed therein and the seal is peeled off, and the one surface is covered with a second peeling sheet and the exposed side is coated with a gel coat having a pigment B mixed therein, and these processes are repeated. ;CONSTITUTION: A surface of a lower mold 12 is coated with a mold release agent, receiving faces (b) and (c) are covered with a peeling sheet 13, and a receiving face (a) is exposed. The receiving face (a) is coated by spraying with a gel coat having a pigment A mixed therein so as to form a paint film 21. The sheet 13 is peeled off, the receiving face (c) is covered with a sheet 14, and a gel coat having a pigment B mixed therein is applied to the end part of the film 21 formed on the receiving faces (b) and (a) in an overlapping manner so as to form a film 22. Lastly, the sheet 14 is peeled off, the exposed receiving face (c) is coated by spraying with a gel coat having a pigment C mixed therein so as to form a film 23. An unsaturated polyester resin sheet 24 to be a base of waterproof pan and a glass fiber unwoven cloth 25 are superposed, pressed by an upper mold, and cured with heat so as to obtain a waterproof pan.;COPYRIGHT: (C)1996,JPO
