A protective clearcoat and/or base color coats the surface
of the original equipment cast aluminum wheels. Surface degradation may develop
if uncoated weights are used. Frequent, repeated automatic car wash cleaning
from facilities using aggressive silicon carbide tipped tire brushes for cleaning
whitewalls and tires may also damage the finish. Once the protective clearcoat
is damaged, exposure to caustic cleaners and/or road salt causes further surface
degradation.
The refinishing of aluminum wheels requires that the wheel surface be
plastic media blasted in order to remove old clearcoat or paint. The re-machining
or the use of chemical strippers is not recommended due to concerns of repair
durability. The service procedure details how to strip, clean and recoat aluminum
wheel rims that are affected by the above condition.
Wheel Refinishing Service Procedure
Caution: To avoid serious personal injury when applying any two part component
paint system, follow the specific precautions provided by the paint manufacturer.
Failure to follow these precautions may cause lung irritation and allergic
respiratory reaction.
- Remove the tire and wheel from the vehicle. Refer to
Wheel Removal
.
- Dismount the tire from the wheel. Refer to
Tire Mounting and Dismounting
.

- Remove the balance weights.
- Use a suitable remover to wipe the following from the wheel.
• | Wipe the excess grease from the wheel. |
• | Wipe the excess wax from the wheel. |
• | Wipe the excess dirt from the wheel. |
| Important: Do not use chemical strippers.
Do not remachine the aluminum wheels.

- Plastic media blast the wheels in order to remove old paint or
clearcoat.
- Mask off the wheels mounting surface and lug nut contact surfaces.
These arears must remain free of paint/clearcoat.
- Light sanding of the wheel, while manually spinning it, may also
be done to restore the circular machined appearance.
- Refer to and follow the individual painting formula and process
provided by the manufacturer of each specific paint system.
- Unmask the wheel.
- Install a new valve stem.
- Clean all wheel mounting surfaces of any corrosion, overspray
or dirt.
- Install the tire to the wheel. Refer to
Tire Mounting and Dismounting
- Rebalance the tire and wheel new coated wheel weights.
- Install the tire and wheel to the vehicle. Refer to
Wheel Installation
