SUBJECT:
LOWER BODY MOLDING (CLADDING) DISCOLORATION (REFINISH PROCEDURE)
MODELS:
1991-1992 SYCLONE, TYPHOON, AND SONOMA GT
Some 1991-1992 Syclone, 1992 Typhoon, and 1992 Sonoma GT vehicles may experience a discoloration or fading appearance on black lower body
molding (cladding package).
These conditions can occur from contaminants or ultraviolet degradation.
To correct this condition, it is necessary to refinish the molding. In order to obtain a good color match of individual pieces, the entire molding (cladding
package) should be removed and refinished.
