In the video, a person is using a power drill to polish the interior of a car. The drill is attached to a polishing pad, which is being used to buff out a scratch on the car's door panel. The person is applying pressure to the drill, causing the polishing pad to spin and smooth out the scratch. The car's interior is a light color, and the scratch is clearly visible before the polishing begins. As the drill moves over the scratch, the scratch becomes less noticeable, indicating that the polishing is working effectively.
