Claim 18:
19. A method of applying a spray treatment onto a surface of an airframe of an aircraft, the method using a set of multiple modular hood units, each modular hood unit of the set including one or more enclosure walls that partially defines a combined enclosure having a shared interior volume, the method comprising:
assembling the set of multiple modular hood units to define the combined enclosure by, for each modular hood unit of the set:
interfacing the airframe with at least two airframe-interfacing edges of the modular hood unit to define a portion of a spray treatment region of the airframe, and
interfacing at least one inter-unit-interfacing edge of the modular hood unit with at least another inter-unit-interfacing edge of a neighboring modular hood unit of the set to form at least a portion of the combined enclosure; and

spraying a treatment fluid onto a surface of the airframe within the spray treatment region bounded by the combined enclosure;
wherein the set of multiple modular hood units are assembled in a vertically stacked configuration or in a suspended configuration from an overhanging surface of the airframe.
