... process is illustrated in Fig. 6 . Before starting the actual laminating process, the mold surface has to be clean and prepared with a suitable mold-release agent, which must be properly cured before the catalyzed gel coat is applied. Gel coat is a tailored pigmented or nonpigmented resin that typically...
