The spray assembly includes a connector configured for operable engagement with a first and second source of component and a source of pressurized fluid, and a tip operably connected to the connector. The tip includes an opening and defines a mixing chamber between the connector and the opening of the tip, and an insert member configured to be received in the mixing chamber. The insert member includes a plurality of radially extending slots on at least one end of the insert. The plurality of radially extending slots is configured to mix the first and second components prior to the mixture exiting the opening in the tip. ## Claims ### Claim 1 A spray assembly for dispensing a mixture, the spray assembly comprising: a connector portion configured for operable engagement with a first source of component, a second source of component, and a source of pressurized air; an elongated portion extending distally from the connector portion, the elongated portion including a first lumen configured for fluid communication with a first source of component, a second lumen configured for fluid communication with a second source of component, and a third lumen configured for fluid communication with a source of pressurized air; a tip assembly operably connected to the elongated portion, the tip assembly defining an opening and a mixing chamber between a distal end of the elongated portion and the opening of the tip assembly, wherein each of the first lumen, the second lumen, and the third lumen are in fluid communication with the mixing chamber; and an insert member received in the mixing chamber, a distal end of the insert member defining an annular recess and at least one radially extending slot, the annular recess and the at least one radially extending slot operating to mix first and second components prior to the combination exiting the opening in the tip assembly. ### Claim 2 (depends on 1) The spray assembly of claim 1, further including a first and a second source of component. ### Claim 3 (depends on 1) The spray assembly of claim 1, wherein the insert member defines a pair of slots. ### Claim 4 (depends on 1) The spray assembly of claim 1, wherein the distal end of the elongated portion is longitudinally spaced from a proximal end of the insert member. ### Claim 5 (depends on 1) The spray assembly of claim 1, wherein the elongated portion includes an inner shaft and an outer sleeve. ### Claim 6 A spray assembly for dispensing a mixture, the spray assembly comprising: a body defining a first lumen configured for fluid communication with a first source of component, a second lumen configured for fluid communication with a second source of component, and a third lumen configured for fluid communication with a source of pressurized air; a tip assembly disposed about a distal end of the body, the tip assembly defining an opening and a mixing chamber between the distal end of the body and the opening of the tip assembly, wherein each of the first lumen, the second lumen, and the third lumen are in fluid communication with the mixing chamber; and an insert member received in the mixing chamber adjacent the opening in the tip assembly, a distal end of the insert member defining at least one radially extending slot for facilitating the mixing of first and second components prior to the mixture exiting the opening in the tip assembly. ### Claim 7 (depends on 6) The spray assembly of claim 6, further including a connector extending proximally from and operably connected to the body. ### Claim 8 (depends on 6) The spray assembly of claim 6, further including a first source of component and a second source of component. ### Claim 9 (depends on 6) The spray assembly of claim 6, wherein the insert member defines a pair of slots. ### Claim 10 (depends on 6) The spray assembly of claim 6, wherein the distal end of the body is longitudinally spaced from a proximal end of the insert member.
