What is Polishing and Define the Process

What is Polishing? A process to generate a reflective surface. Normally, the polish is generated by using a fine-micron or sub-micron abrasive particle in combination with a liquid. Polishing is a "wet" process. Often the polishing process utilizes a pad to contain the abrasive, so polishing may not be a "loose abrasive process.".
