- Progressively Use Finer Grits: Gradually move to finer grits (400-2000) for a smoother finish.
3. Apply Polishing Compound
- Select the Right Compound: Use a coarser compound for initial polishing and switch to a finer one for finishing.
- Use a Polishing Wheel or Pad: Apply the compound evenly to avoid streaks or uneven finishes.
4. Buff the Surface
- Use a clean, soft buffing pad to remove residue and enhance the shine.
5. Inspect and Repeat if Necessary
