ト付き成形品および製法を提供するものである。A conventional method of applying a radical polymerizable resin to a mold in advance, curing the resin, and then molding a molded article containing an unsaturated polyester resin, an inorganic filler, and a reinforcing material as main components is known. In addition, since the mold is contained in both the application and curing time of the radical polymerization resin applied to the mold and the molding time of the molded article, there is a problem that the productivity of the molded article with the gel coat is low. SUMMARY OF THE INVENTION The present invention provides a molded article with a gel coat having excellent productivity for applying a gel coat after removing the molded article from a mold and a production method.
