This bulletin supersedes Dealer Technical Bulletin 84-T-09.
The purpose of this service bulletin is to assist dealerships in repairing the discoloration or surface degradation that has been experienced on certain style
cast aluminum wheels.
A protective clear coating is applied to the surface of original equipment cast aluminum wheels. A surface degradation condition can begin to develop if
frequent, repeated automatic car wash cleaning abrades or wears off the factory applied protective clear coating. This can happen at some automatic car
wash facilities using aggressive silicon carbide tipped tire brushes to clean white walls and tires. Once the protective clear coating is damaged, exposure
to caustic cleaners and/or road salt further causes surface degradation. The following procedure details how to strip, clean and recoat those aluminum
wheel rims that are affected by the above condition.
