Preparing and Spray Painting Window Sills

What happens here

The painter moves to a window sill that has already been masked. He uses an old paint brush to thoroughly dust off the window sill, emphasizing the importance of a clean, smooth surface before painting to ensure a high-quality finish. After dusting, he uses the airless sprayer to apply paint to the window sill, covering all surfaces evenly with horizontal passes.

Goal: Achieve a smooth, clean finish on window sills.
