How to Sand Aluminum Wheels for Paint or Polish: Ultimate DIY Guide

Aluminum wheels can transform the look of any car, but only if they’re smooth and free from corrosion or scratches. Whether you want to paint, clear coat, or polish your rims, sanding is the key first step. This in-depth, SEO-rich DIY guide will show you how to sand aluminum wheels for paint or polish, what grit sandpaper to use, and how to get flawless results at home.

Can You Sand Aluminum Wheels?

Absolutely. Sanding removes clear coat, old paint, corrosion, and minor curb rash, giving you a perfect base for new paint or polish. Always use sandpaper specifically designed for metal for best results.

Best Sandpaper Grits for Aluminum Wheels

• 180–320 grit sandpaper: For stripping paint or heavy corrosion.
• 400–600 grit sandpaper: For smoothing, feathering edges, and prepping for primer or polish.
• 1000–2000 grit sandpaper: For final smoothing before polishing or clear coat.

Step-by-Step: How to Sand Aluminum Wheels

1. Remove the wheels from the car and clean them thoroughly.
2. Strip old paint or clear coat using 180–320 grit sandpaper, working evenly over all surfaces.
3. Smooth the metal with 400–600 grit, focusing on scratches and imperfections.
4. For a mirror polish, wet sand with 1000–2000 grit in circular motions.
5. Wipe clean with a microfiber towel between each grit stage.
6. Finish by polishing with aluminum or metal polish, or apply primer and paint if desired.
