Most original equipment aluminum wheels are clear coated for corrosion resistance. You can generally use any type of wax or sealer specially formulated for alloy wheels, or any product that is designed for a base coat, clear coat finish. CAUTION: Do not use any wax or polish that contains abrasives on a clear coated wheel (chrome polish, rubbing compound, ordinary wax designed for ordinary painted finishes or that "restores faded paint". The abrasives in such products will scratch and dull the clear coat on the wheels.
