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 device, comprising: a fluid delivery tip assembly;an air atomization cap disposed coaxially around the fluid delivery tip assembly, wherein the air atomization cap comprises a shaping air horn configured to deliver shaping air, the shaping air horn comprises a first shaping air horn orifice on an inner wall of the shaping air horn and a first spray fluid passage extending through a section of the inner wall next to the first shaping air horn orifice, and the first spray fluid passage is configured to deliver a first spray fluid next to one or more shaping air streams from the shaping air horn; 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 device of claim 1, wherein the shaping air horn comprises a plurality of air horn orifices on the inner wall. 3. The spray coating device of claim 2, wherein the first spray fluid passage of the shaping air horn extends through the section of the inner wall at least partially between the first shaping air horn orifice and a second shaping air horn orifice of the plurality of air horn orifices. 4. The spray coating device of claim 1, wherein the first spray fluid passage comprises a tube extending through an outer wall of the shaping air horn and through the section of the inner wall. 5. The spray coating device of claim 1, wherein the first spray fluid passage comprises a tube extending along an inner passage of the shaping air horn. 6. The spray coating device of claim 1, wherein the shaping air horn comprises a third spray fluid passage extending through a second section of the inner wall next to the first shaping air horn orifice, and the third spray fluid passage is configured to deliver the first spray fluid next to one or more shaping air streams from the shaping air horn. 7. The spray coating device of claim 1, wherein the first spray fluid is configured to be delivered through the first spray fluid passage using pressure feed techniques, suction feed techniques, or gravity feed techniques. 8. The spray coating device of claim 1, wherein the second spray fluid is configured to be delivered through the second passage using pressure feed techniques, suction feed techniques, or gravity feed techniques. 9. The spray coating device 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. 10. A system, comprising: an air atomization cap having a shaping air horn configured to deliver shaping air, wherein the shaping air horn comprises a first shaping air horn orifice on an inner wall of the shaping air horn configured to deliver shaping air via one or more shaping air streams, a first spray liquid passage configured to deliver a first spray liquid next to the one or more shaping air streams from the first shaping air horn orifice, and the first spray liquid passage comprises a tube extending through a section of the inner wall next to the first shaping air horn orifice. 11. The system of claim 10, wherein the shaping air horn comprises a plurality of air horn orifices on the inner wall, and the tube of the shaping air horn extends through the section of the inner wall at least partially between the first shaping air horn orifice and a second shaping air horn orifice of the plurality of air horn orifices. 12. The system of claim 10, wherein the tube of the shaping air horn extends through an outer wall of the shaping air horn and through the section of the inner wall. 13. The system of claim 10, wherein the tube of the shaping air horn extends at least partially along an inner passage of the shaping air horn. 14. The system of claim 10, comprising a fluid delivery tip assembly having a second spray liquid passage configured to deliver a second spray liquid through a fluid tip exit of the fluid delivery tip assembly. 15. The system of claim 10, wherein the first spray liquid is configured to be delivered through the first spray liquid passage using pressure feed techniques, suction feed techniques, or gravity feed techniques. 16. A method, comprising: delivering one or more shaping air streams from a shaping air horn of an air atomization cap, wherein the shaping air horn comprises a first shaping air horn orifice on an inner wall of the shaping air horn; anddelivering a first spray fluid next to the one or more shaping air streams from the shaping air horn via a first spray fluid passage, wherein the first spray fluid passage extends through a section of the inner wall next to the first shaping air horn orifice. 17. The method of claim 16, comprising selectively adjusting a first pressure or a first flow rate of the first spray fluid through the first spray fluid passage. 18. The method of claim 17, comprising selectively adjusting the first pressure or the first flow rate of the first spray fluid through the first fluid passage based on a second pressure or a second flow rate of a second spray fluid delivered from a fluid tip exit of a fluid delivery tip assembly disposed within the air atomization cap. 19. The method of claim 17, comprising selectively adjusting the first pressure or the first flow rate of the first spray fluid during operation of a spray coating device that comprises the air atomization cap. 20. The method of claim 17, comprising selectively adjusting the first pressure or the first flow rate of the first spray fluid to maintain a viscosity of a combined fluid stream within a desired range, wherein the combined fluid stream comprises the first spray fluid and a second spray fluid.
