DISCUSSION:

To compete and stay in the forefront of paint technology, Chrysler Corporation introduced a stone guard protector material in the 1980's. The stone guard material is applied to varied exterior surfaces on all passenger cars and light trucks. These surfaces can include: Hoods, lower fenders, rocker panels, lower doors, and lower quarter panels.

The following recommended repair procedures are provided by Chrysler paint suppliers, "BASF" and "PPG". Other stone guard repair systems are available. Specific questions should be directed to your local paint distributors.

"BASF" STONE GUARD REPAIR PROCEDURES

1. Wash the entire vehicle with water and a mild detergent soap, rinse thoroughly and let dry.

2. Clean the entire vehicle with R-M 909 Pre-Kleano for California and R-M 900 where the R-M 909 is not available or use Gasurit 541-5.

3. Using a "DA" sander, sand the damaged areas using 80 grit, or finer, to featheredge the damage. Follow with 120 grit and final sanding with 240 grit.

NOTE 1:
EXTEND THE FEATHEREDGE 1-1/2 TO 2 INCHES OUT. THIS WILL PREVENT A BULLS EYE FROM APPEARING WHEN THE JOB IS DONE.

4. Mix either an epoxy primer or self-etch primer (DE 15 or DE 17).

5. Apply 1-2 light coats over the bare metal areas.

6. Allow the material to dry for 15 to 20 minutes before applying the stone ship protector.

7. Apply the Stone Chip Protector Glassohyd 1109-12406 over the prepared areas.

NOTE 2:
GUN TECHNIQUE IS ESSENTIAL. BY CONTROLLING THE SPRAY-GUN OVER THE PREPARED AREA, THE PAINTER CAN FEATHER THE STONE CHIP PROTECTOR AS IT IS BEING SPRAYED. THE WETTER YOU APPLY THE MATERIAL, THE SMOOTHER IT WILL FLOW OUT.

8. Allow the stone chip material to dry. Heat may be used to accelerate the dry times.

9. After the Stone Chip Protector has been applied, it may be top coated with a single or base-clear urethane system.
