Methods and apparatus for vacuum forming and subsequently applying topical coatings fiber-based food containers. The slurry includes one or more of an embedded moisture barrier， vapor barrier， and oil barrier， and the topical coating comprises one or more of a vapor barrier， a moisture barrier， an oil barrier， and an oxygen barrier. For food containers having deep sidewalls， a spray coating system includes a first nozzle for applying a full cone spray pattern to the bottom surface of the container， and a second nozzle for applying a hollow cone spray pattern to the inside surfaces of the side walls.
