The video begins with a close-up shot of a person's hand pointing at a black metal plate with several holes. The person then uses a yellow caulking gun to apply a white substance, likely caulk, into one of the holes. The person's hand is visible throughout the video, and they appear to be working carefully and methodically. The metal plate is situated in a location that is not clearly visible, but it seems to be part of a larger machine or structure. The caulking gun is the only tool used in the video, and the white substance is the only material applied. The video does not contain any text or subtitles.
