How to Repair BMW Rims

1. Research online and at auto shops to find paint and lacquer products that match BMW factory alloys. Purchase the silver spray wheel paint and high-gloss clear lacquer that is compatible with your BMW.
2. Open the utility compartment in the trunk of your BMW to retrieve the wheel lock needed to loosen the lug nuts on your tires. Raise your car using a jack stand. Loosen the lug nuts, using the wheel lock to remove each tire. Place each tire aside in preparation for the rim-cleaning process.
3. Pour paint thinner onto your rims and use a cloth to wipe off grease, brake dust and grime so that the surface is clean. Wait five minutes for the paint thinner to dry.
4. Locate the areas of the rims that are damaged from chipping. Pour auto body filler onto a putty knife and apply it to the damaged areas. Wait approximately 10-15 minutes until the body filler becomes dry to the touch.
5. Sand the auto body filler with100 grit sandpaper. Sand using the 200 grit paper once the 100 grit has worn down. Sand using the 400 grit sandpaper once the 200 grit has worn down and until the auto body filler becomes even with the surface of the rim. Wipe the rims with water and a clean cloth to remove sand and dust. Dry the rims with a clean cloth.
6. Place painters tape around the outside of your rims so that it is between the crevice of the tire and the rim, protecting your tires from rim paint. Tape newspaper around your tires so that only the rims are exposed.
7. Spray three coats of silver wheel paint on the areas of the rims that you applied auto body filler to, allowing 30 minutes between coats.
8. Wait 30 minutes until the last coat of silver wheel paint has dried. Spray the high-gloss clear lacquer on the damaged areas. Repeat this process three times, allowing 30 minutes for each coat to dry.
9. Remove all newspaper and painters tape from your tires. Re-mount the wheels on your BMW.
