Apply & Remove Window Overlay

What happens here

For an optional visual demonstration, hold a piece of paper or cardboard against the car window to create a rectangular stencil. Spray white temporary paint (such as snow spray or a similar easily removable window coating) onto the exposed area of the window. Immediately after applying the white paint, spray a clear liquid (like water or a window cleaning solution) over it, and wipe the area clean with a cloth to show how quickly and easily this specific type of paint disappears from the glass, distinct from the paint on the car door.

Goal: Show a temporary, easily removable window effect
