Some 1988-89 C/K Sportside trucks have experienced star-break type cracking of the rear fender paint due to the impact of stones thrown from the tires.

condition on rear Sportside fenders.

Raise the vehicle on a hoist and remove the rear wheels.

Clean inner fender wells using a coarse brush, water, prep sol (DuPont P/N 39295 or equivalent) and mineral spirits as needed to assure a clean
inner fender surface (figure 1).
3.
Shake the water borne protectant well before using.
SPRAY PROCESS
1.
Attach the spray gun directly to the protectant container.
2.
Hold the spray gun (J38337) with the nozzle at a 45 degree angle and 10 to 12 inches from the surface.
