Preparing the Wheel
1. Removing the Wheel
Use a jack and lug wrench to carefully lift the car and remove the damaged wheel.
2. Cleaning the Wheel
Use a mild detergent and water to thoroughly clean the wheel, removing any dirt or grease. Dry the wheel with a clean microfiber cloth.
3. Masking the Tire
Apply masking tape around the perimeter of the tire where it meets the rim to protect it from paint or sanding.
4. Sanding the Scratched Area
Select sandpaper with a grit appropriate for the severity of the scratch. Start with a coarser grit (e.g., 120-180) for deeper scratches and gradually move to a finer grit (e.g., 220-320) for finishing.
Use a sanding block or orbital sander to sand the scratched area in a circular motion, applying even pressure. Sand just enough to remove the scratch, being careful not to damage the surrounding paint.
Sanding Grit Recommendations:
| Scratch Depth | Initial Sandpaper Grit | Finishing Sandpaper Grit |
|---|---|---|
| Deep/Visible | 120-180 | 220-280 |
| Medium/Feeler-Detectable | 180-220 | 280-320 |
| Light/Nail-Catch | 320-400 | 500-600 |
Cleaning and Sanding the Rim
Before repairing the scratches, it’s crucial to thoroughly clean the rim to remove any dirt, debris, or old paint. This ensures a smooth and effective repair process.
Steps:
-
Rinse the Rim: Use a hose or pressure washer to rinse the rim and remove loose dirt and debris.
-
Apply a Cleaning Solution: Mix a solution of water and dish soap in a bucket. Apply the solution to the rim using a sponge or soft-bristled brush and scrub gently to remove stubborn grime.
-
Dry the Rim: Use a clean, dry cloth to wipe the rim and remove excess moisture. Allow the rim to air dry completely before proceeding to sanding.
-
Sand the Scratch with Coarse Sandpaper: Start by using coarse sandpaper (120-180 grit) to sand down the scratched area of the rim. This removes the damaged metal and creates a smooth surface for repair.
-
Sand with Finer Sandpaper: Switch to finer sandpaper (220-400 grit) to smooth out the sanded area. Sand in circular motions, gradually reducing the grit of the sandpaper until you achieve a smooth, polished finish.
Filling the Scratch with Filler or Putty
Once the scratch has been cleaned and sanded, it’s time to fill it in. You can use either body filler or putty for this. Body filler is a two-part epoxy that is mixed together and then applied to the scratch. Putty is a one-part compound that is simply applied to the scratch. Both body filler and putty will harden over time, filling in the scratch and creating a smooth surface.
Choosing the Right Filler or Putty
There are a few things to consider when choosing a filler or putty for your scratched rim.
– The type of scratch: Some fillers and putties are better suited for certain types of scratches. For example, body filler is better for deep scratches, while putty is better for shallow scratches.
– The material of the rim: The type of filler or putty you need will also depend on the material of the rim. For example, aluminum rims require a different type of filler than steel rims.
– The desired finish: Some fillers and putties will leave a more visible finish than others. If you want a seamless finish, you’ll need to choose a filler or putty that is specifically designed for that purpose.
