Answer
2000 grit refines the surface but does not create shine by itself. Use 3000, then polish.
Why it happens
Very fine sandpaper refines scratches but usually leaves a uniform sanding haze. Shine normally comes from polishing after sanding.
Recommended grit
Use 1500, 2000, then 3000 before polishing. After 3000, use the correct polish for the material.
Wet or dry
Wet for clear coat, plastic, resin, and similar fine finishing work.
Success check
The surface has an even fine haze with no deep scratches before polishing.
What to do
- Wet sand through 1500, 2000, and 3000.
- Keep the surface clean and evenly wet.
- Stop when the haze is uniform.
- Polish after sanding to restore shine.
Avoid: Do not expect 2000 grit alone to create a glossy finish.
