Why Sanding Matters

Sanding levels imperfections and creates uniform tooth so your next layer (primer, paint, stain, clear coat, or polish) goes on evenly.

Recommended Tools

• Sanding block or soft pad (keeps pressure even)
• Microfiber towels (wipe between grits)
• Tack cloth (final dust pickup)
• Spray bottle with clean water (wet sanding)
• Painter’s tape (mask edges/trim)
• Safety glasses and a dust mask

Recommended Grit Sequence

• 80 grit
• 120 grit
• 180 grit
• 220 grit
• 400 grit

Step-by-Step

1. Clean the surface and mask off areas you don’t want to sand.
2. Start with 80 grit to remove defects and level toward remove oxidation and prep for polishing compound.
3. Move to 120 grit and sand until the previous scratches are mostly replaced by finer marks.
4. Wipe clean and inspect under a bright, low-angle light; fix any deep marks before moving on.
5. Continue through 400 grit for final prep. Wet sand where it helps refine the scratch pattern and reduce dust.
6. Remove all residue, let dry, then proceed with your next finishing step.

Special Cases

Edges: Use lighter pressure to avoid sanding through.

Curves: Use a soft pad to follow contours without flattening.

Spot repairs: Feather outward with each grit to blend transitions.

Pro Tips

• Use overlapping passes and keep pressure consistent.
• Clean between grits so coarse particles don’t leave deep random scratches.
• If leveling is slow, step back one grit instead of pressing harder.
• For wet sanding, keep a thin water film and rinse the sheet often.
• Feather outward around repairs so the transition blends after finishing.

Aftercare

• Remove dust or slurry completely and wipe with a clean microfiber towel.
• Let the surface dry fully before applying primer, paint, stain, clear coat, or polish.
• Seal sanding dust in a bag for disposal.

FAQs

• What grit should I use for final smoothing? — Use the finest grit in your sequence that matches the next finish step. Polishing steps require finer grits than paint prep.
• Why do I see scratches after I think I’m done? — A deeper scratch from a lower grit was left behind. Step back one grit and remove it, then move up again.
• How do I prevent contamination between grits? — Wipe the surface and your hands, and change rags if they pick up coarse dust.

Watch & Learn

In the video, watch how the sanding marks become finer and more uniform as the grit increases. That uniformity is what keeps the finish from showing streaks or scratches.
