How to Sand Plastic Car Parts with 800 Grit Sandpaper Sheets

Plastic car parts like bumpers, trim, and mirror housings often require sanding before painting or refinishing. Using the right grit ensures smooth adhesion and a professional finish. eQualle 800 grit sandpaper sheets (9x11 in, Wet or Dry) are an excellent choice for this job.

Why 800 Grit for Plastic Car Parts?

800 grit is a medium-fine abrasive that removes imperfections while leaving a surface smooth enough for paint. It provides the right amount of tooth for primer and paint to bond without scratching or damaging plastic.

Tools You’ll Need

• eQualle 800 Grit Sandpaper sheets (9x11 in, Wet or Dry)
• Bucket of water with mild soap (for wet sanding)
• Sanding block or sponge pad
• Microfiber cloths
• Plastic primer and paint

Step-by-Step: Sanding Plastic Car Parts

1. Clean the surface. Wash thoroughly with soap and water to remove dirt and grease.
2. Wet sand with 800 grit. Use 800 grit (25-pack) sheets soaked in water, sanding lightly and evenly.
3. Check smoothness. Wipe with a microfiber cloth—the surface should look evenly dull.
4. Prime the surface. Apply a plastic adhesion primer after sanding.
5. Paint and finish. Apply paint in thin, even coats for a lasting finish.

Special Cases

For heavily scratched plastics, start with 400–600 grit, then refine with 800. For final smoothing before clear coat, follow with 1000–1500 grit.

Pro Tips

• Always wet sand plastic to avoid melting or gouging.

• Replace clogged sheets promptly for efficiency.

Aftercare

• Protect painted parts with a clear coat for durability.
• Wash gently with non-abrasive cleaners.
• Store sandpaper sheets flat and dry for future projects.
