Condition
Some customers may report star shaped cracks in the paint on fiber glass rear fenders.
Cause
Star shaped cracks in the paint finish are caused by the impact of rocks flung out of the tire treads against the inside of the fiber glass fender.
Correction
Install protective fender liner. The liner is a special polymer layer with an aluminum foil backing that is applied to the inside of the fenders.
Service Procedure
The inner fender must be clean, dry, and the temperature must be above 45°F. Power washing may be necessary. Any after market undercoating must be
removed.
Caution:
To prevent cuts and abrasions on your hands from sharp aluminum foil edges, gloves should be worn during this service procedure.
