Wet sanding is using wet-and-dry fine-grit sandpaper to flatten the paintwork by hand. When polishing a car, we are removing a very thin layer of scratched paint, however the sponge pads we use are not flat, and they are soft, and so if we know we need to cut-back the surface to remove a scratch, we can use a very fine sandpaper on a flat sanding block. This if both faster than polishing and will remove paint more evenly.
Wet and dry sandpaper is special waterproof sandpaper which is designed, so it can be used wet. Using water acts as a lubricant, and we can also wash away dust from the paper.
