Sandpaper Sheets for Auto Body Repair – 9x11 Guide

Auto body repair requires the right sanding process to achieve smooth, paint-ready surfaces. eQualle 9x11 inch Wet/Dry Sandpaper Sheets are trusted by DIYers and professionals for repairing scratches, leveling filler, and prepping panels for paint.

Why Sanding Matters in Auto Body Repair

Car surfaces are coated with primer, basecoat, and clear coat. Imperfections such as scratches, dents, or body filler edges need sanding to blend seamlessly. Without proper sanding, paint won’t adhere, repairs remain visible, and finishes may peel.

Tools You’ll Need

• Sanding block or orbital sander
• Body filler and spreader
• Primer and paint
• Microfiber cloths
• eQualle Wet/Dry Sandpaper Sheets

Best Sandpaper Grits for Auto Repair

• 80 Grit (50-pack) — Shapes hardened body filler and removes rough material.
• 150 Grit (100-pack) — Smooths filler edges and begins blending.
• 320 Grit (25-pack) — Prepares surfaces for primer.
• 600 Grit (50-pack) — Refines primer for paint adhesion.
• 1000 Grit (100-pack) — Smooths clear coat repairs before polishing.

Step-by-Step: Sanding for Auto Body Repair

1. Assess the damage. Clean the panel and mark scratches, dents, or rust spots.
2. Apply filler (if needed). Spread body filler evenly and allow to cure.
3. Sand with 80 grit. Shape filler and remove heavy imperfections.
4. Switch to 150 grit. Smooth transitions between filler and metal.
5. Move to 320 grit. Prepare surfaces for primer application.
6. Sand primer with 600 grit. Level texture for an even basecoat.
7. Finish with 1000 grit. Refine clear coat repairs before polishing and buffing.

Special Cases

For rust repairs, remove corrosion fully before applying filler. For blending new paint into old, sanding with 1000 grit ensures invisible transitions.

Pro Tips

• Always sand in crosshatch patterns for even leveling.
• Use wet sanding for fine grits (600–1000) to avoid scratches.
• Replace sheets often to maintain sharp cutting action.

Aftercare

• Allow paint and clear coat to cure before polishing.
• Wash repaired panels with pH-neutral soap.
• Re-polish with 1000 grit and compound if surface dulls.

FAQs
