Restore Clear Coat on Car Hood with 320, 1000, and 3000 Grit Wet Sanding

Peeling or faded clear coat can make even a well-maintained car look neglected. Using a 320 → 1000 → 3000 grit sanding sequence, you can remove damaged clear and prep the surface for a fresh top coat.

Why This Method Works

320 grit cuts through peeling areas quickly, 1000 grit smooths the transition between bare paint and remaining clear coat, and 3000 grit creates a uniform surface ideal for spraying new clear.

Tools & Materials

• Wet/dry sandpaper: 320 grit (50-pack), 1000 grit (25-pack), 3000 grit (25-pack)
• Dual-action sander or hand sanding block
• Masking tape and plastic sheeting
• Spray bottle with water + dish soap
• Microfiber towels
• Automotive clear coat spray

Recommended Grit Sequence

• 320 grit: Remove failing clear coat. (50-pack)
• 1000 grit: Smooth edges and blend surfaces. (25-pack)
• 3000 grit: Final prep for new clear coat. (25-pack)

Step-by-Step Process

1. Mask and protect. Cover surrounding panels with plastic and tape to prevent overspray and accidental sanding.
2. Initial sanding. Wet sand with 320 grit sandpaper to strip away peeling clear and feather edges.
3. Surface blending. Use 1000 grit sandpaper to smooth the transition between exposed paint and remaining clear areas.
4. Final refinement. Finish with 3000 grit sandpaper for a consistent, satin-smooth surface.
5. Recoat. Apply new clear coat in multiple light passes, allowing proper flash time between coats.

Special Considerations

When working on older paint, check for weak adhesion in surrounding areas—sanding too close to compromised edges can cause more peeling.

Pro Tips

• Always keep the surface wet to prevent clogging and heat damage.
• Use light, even pressure during final sanding for uniform results.
• Allow clear coat to cure fully before buffing.

Aftercare

• Wash with pH-neutral car shampoo.
• Apply wax or ceramic coating after 30 days to protect the finish.

FAQs

• Can I start with 1000 grit if the clear coat is only slightly peeling? Yes—but it will take longer to remove damaged areas.
• Will this work for metallic paint? Yes—just be careful not to sand through to the metallic layer.
• Is 3000 grit necessary? Absolutely—it reduces the sanding marks visible under new clear.
