How to Repair a Curbed Alloy Wheel: A Step-by-Step DIY Guide

Curb rash is a common issue for alloy wheel owners, but repairing the damage yourself can save time and money. This guide provides detailed instructions to restore your wheels to their original glory.

Why Repair Curbed Alloy Wheels?

Curb damage not only detracts from your car’s appearance but can also lead to corrosion over time. Repairing the damage early prevents further issues and helps maintain the wheel’s integrity.

Materials Needed

To repair curbed alloy wheels, gather the following:

  • Sandpaper (grits ranging from 80 to 400)
  • Alloy wheel filler or epoxy putty
  • Primer
  • Spray paint (color-matched to your wheels)
  • Clear coat spray
  • Masking tape and gloves

Step-by-Step Repair Process

  1. Prepare the Wheel:
    Clean the wheel thoroughly to remove dirt and grease. Use soap, water, and a degreaser for best results.
  2. Sand the Damaged Area:
    Start with coarse sandpaper (80-120 grit) to smooth out the scratches and rough edges. Switch to finer sandpaper (300-400 grit) for a polished finish.
  3. Apply Filler Putty:
    For deep scratches or gouges, use alloy wheel filler or epoxy putty. Apply it to the damaged area and smooth it out using a plastic scraper. Let it cure as per the manufacturer’s instructions.
  4. Sand Again:
    Once the filler is dry, sand it with fine-grit sandpaper to ensure it blends seamlessly with the rest of the wheel.
  5. Mask and Prime:
    Mask off the tire and any areas you don’t want to paint. Apply a coat of primer, and let it dry completely.
  6. Paint the Wheel:
    Spray paint in thin, even layers, allowing each coat to dry before applying the next. Usually, 2-3 coats are sufficient.
  7. Apply Clear Coat:
    Finish with a clear coat to protect the paint and give the wheel a glossy finish.

Tips for a Professional Look

  • Work in a well-ventilated area to avoid inhaling fumes.
  • Always wear gloves and safety goggles during the repair process.


Repairing curbed alloy wheels might seem daunting, but with the right tools and patience, you can achieve impressive results. For severe damage, consider consulting a professional.
