Multiple Choice

Which defect in polishing is characterized by circular scratches and is typically corrected by using finer abrasives?

Swirl marks are circular scratches that show up as ring-like patterns on the surface after polishing. They come from the polishing pad moving in a circular path and the abrasive leaving grooves. The way to fix them is to switch to finer abrasives and polishes, refining the finish step by step until the circular scratch pattern is removed and a smooth, glossy surface remains. In simple terms, you’re cutting down the depth of the concentric scratches by using progressively finer abrasives, which blends the marks away. The other defects don’t fit this signature circular pattern: haze is a cloudy milky appearance, orange peel is a texture issue from spraying technique, and micro-marring refers to very fine, often random scratches rather than concentric ones.
