A close-up shot shows a person using a caulking gun to apply sealant around the edge of a piece of glass, presumably a window. The glass is resting on a stand covered with towels. The person's hands are visible as they operate the caulking gun, applying a bead of black sealant into the crevice between the glass and the black rubber frame. The caulking gun is red with a silver nozzle, and appears well-used. In the background, the interior of a workshop is visible, with red cabinets, tools, and a ladder. The lighting is bright. An air compressor with a hose is visible in the foreground.
