What is wet sanding?
Wet sanding is a technique used in car painting to achieve a smooth, flawless finish by removing imperfections in the paint or clear coat. Unlike dry sanding, wet sanding involves using water or a lubricating solution to minimize friction and prevent the sandpaper from clogging with debris. This process is essential for eliminating orange peel texture, dust nibs, scratches, and other surface irregularities.
Wet sanding is typically done after applying a base coat and clear coat, or when restoring an older paint job. It requires fine-grit sandpaper, usually ranging from 1000 to 3000 grit, to gently level the paint surface without causing deep scratches. The process begins by soaking the sandpaper in water to ensure smooth sanding. Using light pressure, the sandpaper is moved in a back-and-forth or circular motion, constantly keeping the surface wet to avoid damaging the paint.
Once wet sanding is complete, the surface is polished and buffed to restore gloss and shine. This step is crucial to achieving a professional-grade finish. While wet sanding can be done by DIY enthusiasts, it requires patience and precision to avoid burning through the paint layers. For best results, many car owners rely on professional auto detailers or painters.
