K 2500 Truck 4WD V6-262 4.3L (1988)
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.
1.
Attach the inboard center section of the liner to the inboard center section of the fender first. Remove a small section of the protective wax paper
on the inboard center section of the liner to expose the adhesive layer of the fender liner. Using moderate pressure, apply the top fender liner to the
inside top of the fender as illustrated (Figure 1). Carefully peel the wax paper from the center of the liner toward the front and rear of the fender
attaching the liner as you go. Repeat this process to the opposite fender.
2.
Apply the rear fender liner to the inside rear of the fender as illustrated (Figure 1). Take care to overlap the rear liner on the top liner as illustrated.
Repeat this process to the opposite fender.
3.
Apply moderate pressure to the entire surface of the fender liners to insure good adhesion to the inside of the fenders.
