What is the purpose of rotating the air horns of the spraygun?

Rotating the air horns of the spray gun serves to match the angle of the panel being painted, which is crucial for achieving an even and consistent coating. When the angle of the panel varies, such as in contours or vertical versus horizontal surfaces, adjusting the air horns allows the spray pattern to be oriented optimally for that specific surface. This adjustment ensures that the paint is distributed uniformly, reducing the chances of overspray or missed sections, which ultimately enhances the quality of the finish.

In terms of practical application, when you are painting a complex shape or in an awkward position, being able to rotate the air horns helps in maintaining control over the application without needing to reposition the entire spray gun. This capability is essential for professional results in automotive painting and refinishing, where precision is key.
