Zusammenfassung:	PURPOSE:To simplify an impregnation and defoaming process, to reduce labor and to increase a molding cycle by spraying a composition consisting of a hollow filler and a specific resin containing a thixotropy imparting agent and a fiber reinforcing material on the single surface of a molded product composed of a specific resin to cure the same. CONSTITUTION:A compsn. consisting of a spherical hollow filler and an unsaturated polyester resin or a vinyl ester resin containing a thixotropy imparting agent and a fiber reinforcing material are sprayed on the single surface of a molded article made of the unsaturated polyester resin or the vinyl ester resin to be cured. Herein, the viscosity of the unsaturated polyester resin and/or the vinyl ester resin containing the spherical hollow filler and the thixotropy imparting agent is 10-50 poise and the thixotropy thereof is pref. 4-9. Further, the spherical hollow filler pref. has a diameter of 10-300mum and specific gravity of 0.02-0.8. The content of the filler is pref. 5.0-60% by volume of the unsaturated polyester resin and/or the vinyl ester resin.
