Which method reduces dust and scratches during sanding by using water?

• A. Dry sanding
• B. Wet sanding
• C. Polishing
• D. Buffing

Answer: (B)

Wet sanding uses water to lubricate the surface and the abrasive, which cools the work and helps the abrasive cut more evenly. The water also traps dust and carries debris away, keeping the area cleaner and reducing the amount of dust that becomes airborne. With less heat buildup and less loading of the abrasive, the sanding action stays smooth, producing fewer scratches and a finer finish. This approach is especially useful when refining finishes in collision repair, such as on clear coats or delicate panels. Dry sanding, polishing, and buffing serve different purposes and don’t provide the same dust reduction and cooling benefits during the sanding step.
