Embodiments of a spray gun incorporating techniques for delivering a spray fluid between, next to, or inside of horn holes of an air atomization cap are provided. In accordance with certain embodiments, the spray gun includes a fluid delivery tip assembly. The spray gun also includes an air atomization cap disposed coaxially around the fluid delivery tip assembly, wherein the air atomization cap comprises one or more shaping air horns configured to deliver shaping air, and each shaping air horn comprises a first spray fluid passage configured to deliver a first spray fluid between, next to, or inside of one or more shaping air streams from the shaping air horn. The spray gun also includes a second spray fluid passage configured to deliver a second spray fluid to a fluid tip exit of the fluid delivery tip assembly.

1. A spray coating gun, comprising: a fluid delivery tip assembly;an air atomization cap disposed coaxially around the fluid delivery tip assembly, wherein the air atomization cap comprises one or more shaping air horns configured to deliver shaping air, and each shaping air horn comprises a first spray fluid passage configured to deliver a first spray fluid inside of one or more shaping air streams from the shaping air horn, wherein each shaping air horn comprises a shaping air horn orifice on an inner wall of the shaping air horn, the first spray fluid passage comprises a tube extending through the shaping air horn orifice, and a shaping air stream of the one or more shaping air streams flows around the tube through the shaping air horn orifice; anda second spray fluid passage configured to deliver a second spray fluid to a fluid tip exit of the fluid delivery tip assembly. 2. The spray coating gun of claim 1, wherein the first spray fluid is delivered through the first spray fluid passage using pressure feed techniques, suction feed techniques, or gravity feed techniques. 3. The spray coating gun of claim 1, wherein the second spray fluid is delivered through the second spray fluid passage using pressure feed techniques, suction feed techniques, or gravity feed techniques. 4. The spray coating gun of claim 1, wherein the first spray fluid comprises a first component material and the second spray fluid comprises a second component material different than the first component material. 5. A system, comprising: an air atomization cap having one or more shaping air horns configured to deliver shaping air, wherein each shaping air horn comprises a first spray fluid passage configured to deliver a first spray fluid inside of one or more shaping air streams from the shaping air horn, wherein each shaping air horn comprises a shaping air horn orifice on an inner wall of the shaping air horn, the first spray fluid passage comprises a tube extending through the shaping air horn orifice, and a shaping air stream of the one or more shaping air streams flows around the tube through the shaping air horn orifice. 6. The system of claim 5, wherein the first spray fluid is delivered through the first spray fluid passage using pressure feed techniques, suction feed techniques, or gravity feed techniques. 7. The system of claim 5, comprising a fluid delivery tip assembly having a second spray fluid passage configured to deliver a second spray fluid through a fluid tip exit of the fluid delivery tip assembly. 8. A method, comprising: delivering a first spray fluid inside of shaping air streams delivered from a shaping air horn of an air atomization cap, wherein delivering the first spray fluid comprises delivering the first spray fluid via a tube extending through a shaping air horn orifice on an inner wall of the shaping air horn, and a first shaping air stream of the shaping air streams is delivered around the tube through the shaping air horn orifice. 9. The spray coating gun of claim 1, wherein each shaping air horn comprises one or more guides extending from the inner wall of the shaping air horn, wherein the one or more guides position the tube within the shaping air horn orifice. 10. The spray coating gun of claim 9, wherein the one or more guides comprise prong-like extensions extending from the inner wall of the shaping air horn. 11. The system of claim 5, wherein each shaping air horn comprises one or more guides extending from the inner wall of the shaping air horn, wherein the one or more guides position the tube within the shaping air horn orifice. 12. The system of claim 11, wherein the one or more guides comprise prong-like extensions extending from the inner wall of the shaping air horn. 13. The method of claim 8, comprising selectively adjusting a pressure or flow rate of the first spray fluid through the tube. 14. The method of claim 13, comprising selectively adjusting the pressure or the flow rate of the first spray fluid through the tube based on a pressure or flow rate of a second spray fluid delivered from a fluid tip exit of a fluid delivery tip assembly disposed coaxially within the air atomization cap. 15. The method of claim 13, comprising selectively adjusting the pressure or the flow rate of the first spray fluid during calibration of a spray coating gun that comprises the air atomization cap. 16. The method of claim 13, comprising selectively adjusting the pressure or the flow rate of the first spray fluid during operation of a spray coating gun that comprises the air atomization cap. 17. The method of claim 13, comprising selectively adjusting the pressure or the flow rate of the first spray fluid to maintain a viscosity of a combined fluid stream including the first and second spray fluids within a desired range. 18. The method of claim 8, comprising delivering the first spray fluid through the tube using pressure feed techniques, suction feed techniques, or gravity feed techniques. 19. The spray coating gun of claim 1, wherein the tube extends through an outer wall of the shaping air horn. 20. The system of claim 5, wherein the tube extends through an outer wall of the shaping air horn.
