An apparatus for applying powder coating material onto large objects such as automotive, truck or other vehicle bodies (32) includes a powder spray booth (12) defining a controlled area (30) within which to apply powder coating material onto the vehicle bodies (32), a powder kitchen (14) located at a remote position from the powder spray booth (12), and a number of feed hoppers (68, 96) located proximate the booth which receive powder coating material from the powder kitchen (14) and supply it to automatically or manually manipulated powder spray guns (42, 46) associated with the spray booth (12) . Oversprayed powder coating material is removed from the spray booth (12) interior by a powder collection and recovery system (16) which transmits the oversprayed powder back to the powder kitchen (14) for recirculation to the powder spray guns (42, 46).
