Which material is used to remove scratches after filing on metal or plastic?

Explanation:
After filing, you need an abrasive method that gradually smooths the surface to erase the filing scratches. Wet and dry paper is ideal because it comes in a range of grits and is used with water to keep the action cool and prevent clogging. By starting with a coarser grit and moving to finer ones, you can level the scratches and produce a smooth, even finish on both metal and plastic. Metal polish is for bringing a finished surface to a shine, not effectively removing the deeper scratches left by filing. Emery cloth can smooth surfaces but is less uniform and harder to control for a fine finish. Bench shears are cutting tools and not used for finishing surfaces.
