6.2 Polishing Techniques
- Apply a small amount of polishing compound directly to the pad or the work surface.

- Maintain light to moderate pressure. Excessive pressure can generate heat and damage the surface.
- Work on small sections at a time (e.g., 2x2 feet) to ensure the compound does not dry out.
- Wipe off excess compound with a clean microfiber cloth after each section.
