Utilize Top-to-Bottom Spraying Direction

What happens here

When spraying the garage door, always move the spray gun from top to bottom. Avoid spraying from right to left across the entire width of the door. Spraying horizontally requires you to walk back and forth along the length of the door, which makes it more difficult to maintain a consistent speed and distance, often resulting in an uneven spray pattern. By spraying vertically, you can maintain a more uniform motion.

Goal: Maintain a consistent and even spray pattern by using the recommended vertical spraying motion.
