How to fix scratched rims

Clean your rims

Make sure the rims are nice and clean before you begin working on the repairs. Do an initial wash with a microfiber cloth and mild cleaner.
After the first wash, put on the rubber gloves and wash the rims again with paint thinner. Dip a cloth in paint thinner and rub it all over the rim. It should have the power to break down any remaining dust, dirt, or debris. While you’re cleaning the wheels, take note of any dents and scratches.
Use a lint-free cloth to dry your rims or let them air dry before moving on to the next step.

Tape your tires

Apply masking tape to the rubber tire surface behind your rims. 1-2 inches of coverage should do the trick; this will prevent you from accidentally sanding your tire.

Sand the scratches

Using 240-grit sandpaper, smooth the rough edges of scratches and small dents. Hold your sandpaper over the surface of the damaged area and gently rub until it is smooth to the touch. Wipe with a damp microfiber cloth to remove the residue.

Fill in scratches and dents with putty

Use metal-reinforced spot putty to fill the scratches and dents. Using a putty knife, scrape a small amount of putty from the container. Apply it to the damaged area with pressure and spread it around with the putty knife. Maintaining consistent pressure will ensure that every scratch and dent is adequately filled.
Afterward, use your fingers to smooth the putty so there are no raised areas.
Let the putty dry according to its instructions (usually around two hours).

Sand the putty

Using 400-grit sandpaper, smooth any remaining raised areas. Continue until the previously damaged area is level and uniform.

Put on safety gear

Before you apply the primer or the spray paint, put on the necessary safety equipment, namely, goggles, gloves, and a respirator.
Paint and primer are dangerous to inhale, so the proper safety equipment is essential.

Cover your wheel with tape and kraft paper

Cover the areas of the tire you aren’t painting in tape and kraft paper. Keep in mind, only the previously damaged areas should be uncovered. You do not need to paint the entire rim.

Apply a metal alloy primer

Stand 6 inches away from the rim and spray a metal alloy primer on the damaged area. A single coat will usually suffice. Allow the primer to completely dry (which usually takes 30 minutes to an hour).

Paint the rim

Stand 10-inches away from the rims and apply a base coat of silver metallic spray paint. Allow the paint to dry according to the product’s instructions. Apply an additional 1-2 coats, as needed.
If your car paint was also damaged along with the rims, you might consider home remedies for removing scratches from car paint.

Apply a spray lacquer

Lacquers prevent the wheels from chipping, scratching, and flaking. Apply a spray lacquer to seal your paint job. Allow to dry according to the product’s instructions before taking your fresh rims for a spin.
If the scratches are still visible on your rims after using these steps, it may be time to take your car to a detailer or auto body shop.
