The DV1 Basecoat Gun is a versatile and efficient tool used in automotive refinishing for applying basecoats. It is important to understand the proper gun settings to achieve optimal results. In this article, we will discuss the various settings and their impact on the basecoat application process.

Gun Pressure

One of the key factors in achieving a successful basecoat application is the gun pressure. The ideal pressure setting for the DV1 Basecoat Gun is typically between 18-22 psi (pounds per square inch). This range provides a good balance between atomization and material flow.

Fluid Tip Size

The fluid tip size plays a crucial role in achieving the desired atomization and pattern size. For basecoat application, a fluid tip size of 1.3-1.4mm is commonly used. This size allows for a fine mist of paint particles, ensuring even coverage and a smooth finish.

Air Cap Selection

The choice of air cap can significantly impact the atomization and pattern shape. The DV1 Basecoat Gun offers a variety of air cap options, including HVLP (High Volume Low Pressure) and Trans-Tech. HVLP air caps are commonly used for basecoat application, as they provide excellent transfer efficiency and reduce overspray.

Fluid Control

Proper fluid control is essential for achieving the desired paint flow and consistency. The DV1 Basecoat Gun features a fluid control knob that allows for precise adjustment of the material flow. It is recommended to start with a lower fluid flow setting and gradually increase it until the desired coverage is achieved.

Pattern Adjustment

The DV1 Basecoat Gun allows for easy pattern adjustment, enabling painters to customize the shape and size of the spray pattern. By rotating the air cap or adjusting the fan control knob, painters can achieve anything from a narrow round pattern to a wide oval pattern, depending on the requirements of the job.


In addition to the gun settings, proper spraying technique is crucial for a successful basecoat application. It is recommended to hold the gun approximately 6-8 inches away from the surface and move the gun in a smooth, overlapping motion. Maintaining a consistent distance and speed helps to achieve an even application and minimize the risk of runs or sags.

Cleaning and Maintenance

To ensure optimal performance and longevity of the DV1 Basecoat Gun, regular cleaning and maintenance are essential. After each use, it is important to thoroughly clean the gun using appropriate cleaning solvents. Additionally, regular inspection and replacement of worn or damaged parts will help to maintain consistent performance.


The DV1 Basecoat Gun is a reliable and efficient tool for basecoat application. By understanding and correctly adjusting the gun settings, painters can achieve optimal atomization, coverage, and finish. Proper technique, regular cleaning, and maintenance are also crucial for achieving consistent results. With the right combination of settings and skills, the DV1 Basecoat Gun can help painters achieve professional-quality basecoat applications.
