A coating may be incorporated in a molded composite article made via a process in which neither the coating nor the resin contact the mold surface. A multilayer sandwich structure is formed having two outside layers of flexible membranes, typically made of silicon. An interior dissolvable film is disposed between the two outer flexible membranes. A layer of fiber reinforcement is disposed between the dissolvable film and one of the flexible membranes. A coating is distributed between a flexible membrane and the dissolvable film, opposite the side having the reinforcement, wherein the film is only slowly soluble, or insoluble, in the coating. The coating is allowed to at least partially cure and a resin is infused through the reinforcement wherein the dissolvable film rapidly dissolves in the resin. The sandwich structure is formed around a mold and the resin is allowed to cure.
