Curb rash is a common and frustrating cosmetic issue that affects car wheels, especially alloy or aluminum rims. It usually happens when your wheel scrapes against a curb or other hard surface, leaving behind scuffs, scratches, or gouges. While curb rash doesn’t typically affect the performance of your wheels, it can detract from the appearance and resale value of your vehicle. Fortunately, fixing curb rash can be a DIY job if you’re willing to put in a bit of effort. In this blog post, the experts from Top Notch Body Shop & Mechanic share how to restore your wheels and get them looking like new.
Assessing the Damage
Before diving into repairs, take a close look at the extent of the curb rash. Light surface scratches are much easier to fix than deep gouges or cracks. If you notice any structural damage to the wheel, such as a bent rim or deep cracks, it’s best to take the car to a professional. However, for minor to moderate scuffs and scrapes, a simple repair kit and a little patience can go a long way.
Cleaning & Preparing the Wheel
Start by thoroughly cleaning the affected wheel. Use soap and water to remove any dirt, grime, and brake dust. Once it’s dry, use a degreaser or rubbing alcohol to ensure the surface is completely clean. Then, sand the damaged area with fine-grit sandpaper (around 240 to 400 grit) to smooth out rough edges. The goal is to create a uniform surface where the filler can bond effectively.
Filling & Smoothing the Area
If the rash is deep, apply a metal-reinforced filler or putty specifically made for automotive wheels. Follow the product instructions and use a plastic applicator to smooth the filler over the damaged area. Allow it to dry completely—this may take several hours depending on the product. Once dry, sand the area again using a finer grit sandpaper (around 600 to 800 grit) to blend it into the rest of the wheel. The smoother the surface, the better the final result will look.
Priming & Painting
Next, apply a primer designed for metal surfaces. This step is crucial to help the paint adhere and to prevent rust. After the primer has dried, apply matching wheel paint in light, even coats. Be sure to allow each coat to dry before applying the next. This process might require two or three coats for full coverage. Finish off the paint job with a clear coat to protect the surface and add shine. Let the wheel cure completely according to the paint manufacturer’s instructions.
Final Touches & Maintenance
Once the repair is complete and the paint has cured, you can polish the wheel to match the shine of the others. While this repair method can significantly improve the look of your wheels, regular maintenance—such as careful driving and proper tire pressure—can help prevent future curb rash. If you want a more flawless or professional finish, consider having the wheels refinished by an auto body shop.
