First, consider which spray gun feed style you would like.

• Gravity-Feed:  With the cup above the gun, gravity-feed models are perfect for smaller jobs and tight spaces. They offer better maneuverability and are easier to clean, making them a favorite for detailed work like cabinetry.

• Bottom-Feed:  Ideal for larger projects, these guns have the fluid cup beneath the gun, allowing for higher capacity (up to 1 quart). This setup is well-balanced and reduces the need for frequent refills, making it suitable for extensive spraying tasks.
