A method of making hollow, fiber-reinforced resin articles having a resin-rich interior coating is disclosed. The interior coating provides a chemically resistant surface and inhibits wicking of fluids through the sidewall of the tank which tends to degrade the resin. The coating is formed by positioning a hollow lay-up of loosely felted reinforcing fibers against the inner surface of a rigid mold having a cylindrical wall portion and domed end portions. A polyester fiber surfacing fabric is placed against the inner surface of the lay-up. The surfacing fabric and lay-up are compressed against the mold wall by a pressurized inflatable core to hold the fabric and lay-up in place. A metered amount of a thermosetting resin is injected into the mold, and the pressure of the inflatable core is increased to compress the lay-up, to evenly distribute the resin throughout the lay-up, and to form a resin-rich coating with said surfacing fabric.
