Which process rubs a material with fine abrasives to produce a smooth, shiny and glossy finish?

• A. Polishing
• B. Linishing
• C. Buffing
• D. Grinding

Answer: (A)

Finishing a surface to a smooth, glossy look by rubbing with very fine abrasive particles is polishing. This process removes the tiniest surface scratches and imperfections, using progressively finer grit until the surface achieves a mirror-like shine. Linishing uses coarser abrasives to level the surface, producing a smooth but not highly reflective finish. Buffing can also yield high gloss, but it relies on a polishing compound on a soft wheel rather than the fine abrasive steps that define polishing. Grinding uses a coarse wheel to remove material quickly and leaves a rougher surface rather than a glossy finish. So the description best matches polishing.
