A pair of vertical guide supports are slidably received in horizontally spaced rails removably mounted on a vertical target surface to be treated, such as the hull of a ship. A rack support interconnects the vertical guide supports and is vertically displaceable relative thereto with a rack plate thereby positioned in spaced relation to the target surface. A treatment device such as a pressurized paint ejector is positioned on the rack plate for selectively imposed movement therewith along linear paths to positions at which it is aligned perpendicular to the target surface to be completely treated by application or removal of paint for example.
