Scratches and dents can diminish the appearance of your alloy wheels. However, if the damage to your alloy rim is minor, you can usually rebuild it yourself. Clean your tires thoroughly before repairing the damage to ensure that any changes you make are as long-lasting as possible. Then, improve their quality and keep them looking excellent; sand, fill and polish your alloy rims.
Examine your rim for any damage
Before you begin, clean the rim thoroughly, then ensure that your repairs last as long as possible. Examine the perimeter for scrapes, dents, or other flaws that may need to be repaired later.
Apply paint thinner
Paint thinner is used to clean the rim. Any remaining dust or dirt on edge can be removed using paint thinner. Dip a towel insolvent and gently cover the rim with it. Rub the area with pressure until the dirt falls off.
Precaution: As a safety precaution, use gloves and a mask while handling paint thinner.
Use a lint-free cloth and let dry the rim. Ensure your wheel is completely dry before you begin repairing the rim damage. After cleaning the wheels, wipe them down with a clean, lint-free cloth or let the rim air dry if you have a moment.
Sanding and filling damage
Masking tape should be used to cover the tire. Tape your tire beneath the rim and 1–2 inches (2.5–5.1 cm) around it using masking tape. This will prevent anything from getting on your tires while you sand the scrapes away and use paint to overlay your repairs.
Scratches the sand and uses the sandpaper grit, which is 240. To smooth off any rough edges, use sandpaper to rub any cracks and minor dents. Rub your sandpaper back and forth over the surface while holding it over the damaged region. Sand the rim’s corrosion until the scrapes or cuts look smooth rather than rough.
- Using a dry cloth, wipe away any dirt from the sandpaper.
- Metal-reinforced spot putty can be used to fill in scratches and dents. With a putty knife, remove a little quantity of spot patch from its container.
- Put the spot with pressure to the damaged area, spreading it out with the palette knife. This will aid the putty in filling up any scratches or dents. To avoid raised spots on your rim, form the putty with your fingers and spread it over the damage.
- Try keeping the spot putty inside the affected area since it can cause ugly lumps if applied to flat, non-damaged regions.
- For a smoother finish, sand the putty with 400-grit sandpaper. Once the putty is entirely dry, smooth away any high leftover spots generated with 400-grit sandpaper.
- Keep your sandpaper so over putty-filled regions and rub it backward and forth until the elevated parts seem to level with the remainder of the rim.

How to apply primer and paint (step by step)?
- Before priming or painting, put on glasses, a respirator, and gloves. Spray paint and primer can irritate the skin, eyes, and lungs. If you begin to feel sick or lightheaded, get out of the area right once and call Poison Control for help.
- To avoid irritation, spray in a well-ventilated environment.
- Tape and craft paper are used to mask your wheel. Wrap craft paper around your tire and any sections of the rim you won’t be painting, then fix it using masking tape to keep it in place. Because metallic spray paint is difficult to remove, protect as many of your rollers as possible to avoid staining.
- Only the deformations should stay revealed, as you don’t need to condemn an entire rim.
- Over the damaged area, apply a metal alloy primer. A primer will make the paint appear more natural and adhere better to your rim.
- Spray the damaged area in sweeping strokes while standing 6–8 inches (15–20 cm) apart from the rim. A single priming application is sufficient to ensure that the spray paint adheres evenly.
- Allow 30 to 60 minutes for the primer to dry. Check the primer’s directions to discover how long you should wait before applying the paint. In general, the period should be between 30 and 60 minutes. Wait until your priming application is dry before spray painting.
- Spray the damaged area with a base layer of metallic spray paint. Select a spray paint color that exactly resembles the silver hue of the alloy rim. Place the spray paint can 10–12 inches (25–30 cm) apart from the edge and use a sweeping motion to paint the area.
- Allow 30-60 minutes for the spray paint to dry. Allow 30 minutes to an hour for your coat to smooth out. To avoid smearing your spray paint, don’t touch it while it dries.
- Consult your paint’s directions for accurate drying timeframes.
- Apply 2-3 more coats of spray paint. Apply additional coats once the first one has dried to get the desired hue. For a natural-looking finish, you’ll need at least 2-3 coats in most circumstances.
- In between coats, don’t touch the paint.
- To preserve the paint finish, use spray lacquer. Paint lacquers protect your spray paint from scratching and flaking. Apply the color in a gentle mist, as you did with the spray paint, and let it dry. The time it takes for the lacquer to cure varies depending on the color, but it usually takes between 8 and 24 hours.
