Ultimate Gloss Sequence: 400, 1200, 2000, and 3000 Grit Sanding

When you need a surface that shines like glass, the 400 → 1200 → 2000 → 3000 grit sanding sequence offers a professional-grade finish. This progression works beautifully for automotive detailing, furniture restoration, and high-end woodworking.

Why This Sequence Works

400 grit removes minor imperfections and levels the surface. 1200 grit smooths and refines, 2000 grit erases fine marks, and 3000 grit produces an ultra-fine surface ready for polishing.

Tools & Materials

• Orbital sander or hand sanding block with soft pad
• Wet/dry sandpaper in 400, 1200, 2000, and 3000 grit
• Spray bottle with water + drop of dish soap
• Microfiber cloths
• Fine polishing compound

Recommended Grit Sequence

• 400 grit: Level and smooth the surface. (25-pack)
• 1200 grit: Refine and remove 400 grit scratches. (25-pack)
• 2000 grit: Eliminate fine haze and prep for ultra-fine sanding. (25-pack)
• 3000 grit: Perfect the surface for polishing. (25-pack)

Step-by-Step Sanding Process

1. Initial sanding. Use 400 grit to level imperfections and create a smooth base.
2. Intermediate smoothing. Switch to 1200 grit to refine the texture.
3. Fine sanding. Move to 2000 grit for removing haze and preparing for final sanding.
4. Final sanding. Finish with 3000 grit to achieve a satin sheen before polishing.
5. Polish. Apply a fine compound and buff to a mirror gloss.

Special Cases

On heat-sensitive finishes, keep the surface wet and use minimal pressure to avoid damage.
