Introduction
Curb rash is a common issue for car owners, causing unsightly scratches and scuffs on wheels. While it may seem like a professional repair job, fixing curb rash is a straightforward process that you can do at home with the right tools. This guide will walk you through how to repair curb rash step by step, restoring your wheels to their original look.
1. What Causes Curb Rash?
Curb rash occurs when a wheel scrapes against a curb or rough surface, resulting in scratches, gouges, or scuffs. Common causes include:
- Parking too close to curbs
- Hitting potholes or road debris
- Making tight turns near sidewalks
- Low-profile tires offering less rim protection
2. Tools & Materials Needed
Before starting the repair, gather the following items:
✔️ Sandpaper (80, 220, 400, and 600 grit) ✔️ Metal file (for deep gouges) ✔️ Rubbing alcohol or wheel cleaner ✔️ Body filler or metal epoxy (for deep damage) ✔️ Primer and matching wheel paint ✔️ Clear coat spray ✔️ Masking tape and plastic sheeting ✔️ Microfiber cloth ✔️ Gloves and protective eyewear
3. Step-by-Step Guide to Fixing Curb Rash
Step 1: Clean the Wheel
- Wash the wheel thoroughly using soap and water.
- Dry it completely with a microfiber cloth.
- Use rubbing alcohol or wheel cleaner to remove grease and dirt.
Step 2: Sand the Damaged Area
- Use 80-grit sandpaper to smooth out rough edges.
- If there are deep gouges, use a metal file to even out the surface.
- Progressively use 220, 400, and 600-grit sandpaper to refine the surface.
Step 3: Apply Filler for Deep Scratches
- For deeper scratches, mix and apply metal epoxy or body filler.
- Let it dry according to the manufacturer’s instructions.
- Once hardened, sand it smooth with 400-grit sandpaper.
Step 4: Mask the Surrounding Area
- Use masking tape and plastic sheeting to cover the tire and prevent overspray.
- Ensure only the damaged area is exposed.
Step 5: Apply Primer and Paint
- Spray a thin layer of primer and let it dry for 15-30 minutes.
- Apply light coats of matching wheel paint, waiting 10-15 minutes between coats.
- Let the paint cure fully (refer to manufacturer instructions).
Step 6: Apply Clear Coat
- Spray two to three layers of clear coat for a glossy, protective finish.
- Allow the wheel to dry for at least 24 hours before driving.
4. Common Mistakes to Avoid
❌ Skipping the sanding process – This can cause rough or uneven repairs. ❌ Applying too much filler – Excess filler can lead to an uneven finish. ❌ Not waiting for paint to dry – Rushing the process can cause peeling or bubbling. ❌ Forgetting the clear coat – Without a protective clear coat, the repair won’t last.
5. When to Seek Professional Help
If the curb rash is extensive or on high-end alloy wheels, professional refinishing may be a better option. Seek help if:
- The damage extends across multiple wheels.
- There are deep cracks or structural damage.
- You prefer a flawless, factory-finish repair.
Final Thoughts
Fixing curb rash is a simple DIY project that can restore your wheels’ appearance and protect them from further damage. By following the right steps, using quality materials, and allowing adequate drying time, you can make your wheels look like new again.
