eQualle Sandpaper Sheets for Auto Body Filler Smoothing (80–400 Grit Guide)

Auto body filler is essential for repairing dents and scratches, but sanding determines whether the repair blends seamlessly or remains visible. eQualle 9x11 inch Wet/Dry Sandpaper Sheets provide the grit sequence needed for smooth, paint-ready surfaces.

Why Sanding Body Filler Matters

Fresh body filler cures hard but uneven. Sanding shapes it, levels transitions, and creates a uniform texture for primer and paint. Without sanding, repairs appear rough and paint won’t adhere evenly.

Tools You’ll Need

• Sanding block or orbital sander
• Body filler spreader
• Vacuum and tack cloth
• Automotive primer
• eQualle Wet/Dry Sandpaper Sheets

Best Sandpaper Grits for Body Filler

• 80 Grit (25-pack) — Shapes and levels fresh filler.
• 120 Grit (50-pack) — Smooths rough sanding marks.
• 220 Grit (100-pack) — Refines filler edges into surrounding metal.
• 400 Grit (25-pack) — Final sanding before primer and paint.

Step-by-Step: Sanding Auto Body Filler

1. Apply filler. Spread smoothly and allow to cure fully.
2. Start with 80 grit. Shape the repair, removing excess material.
3. Switch to 120 grit. Smooth transitions and refine contours.
4. Move to 220 grit. Blend filler edges into surrounding body panels.
5. Finish with 400 grit. Lightly sand for a paint-ready surface.
6. Prime & paint. Seal filler with primer before applying color coats.

Special Cases

For deep dents requiring thick filler layers, repeat sanding with 80–120 grit until shape is correct. For feathering edges, focus on 220–400 grit to create seamless transitions.

Pro Tips

• Always sand with a block to keep surfaces flat.
• Sand in cross-hatch patterns for even shaping.
• Replace sandpaper as soon as it clogs with filler dust.

Aftercare

• Inspect repaired areas under bright light for imperfections.
• Re-sand lightly with 400 grit if primer raises fibers or edges.
• Store unused filler and sandpaper in dry areas.

FAQs

• Can I paint directly over filler? No, always sand smooth and apply primer first.
• What grit is best for blending edges? 220 grit ensures seamless transitions.
• Do I need power tools? Not always—hand sanding works well for small repairs.
