#### SUBJECT: INFORMATION - THERMOPLASTIC REPAIR INCLUDING FRONT IMPACT BEAM

#### MODELS: 1997 CHEVROLET MALIBU 1997 OLDSMOBILE CUTLASS

THE XENOY IMPACT BEAM HAS BEEN ENGINEERED TO WITHSTAND SLIGHT IMPACTS (5 MPH OR LESS), AND SUSTAIN LITTLE OR NO DAMAGE. HOWEVER, IN SOME INSTANCES, THE IMPACT BEAM WILL DEFORM FROM ITS ORIGINAL STATE. FOLLOWING THIS PROCEDURE WILL ALLOW THE TECHNICIAN TO REPAIR AN IMPACT BEAM AND RETURN THE VEHICLE TO ITS ORIGINAL CRASHWORTHINESS. HOWEVER, IF BEAM IS CRACKED, REPLACE IT. THERE ARE 3 BASIC THERMOPLASTIC REPAIR METHODS AS FOLLOWS:

1. IDENTIFY PLASTIC

2. CLEAN

3. REPAIR

DETAILED REPAIR PROCEDURE:

1. REMOVE THE PART FROM THE VEHICLE.

2. IDENTIFY PLASTIC - LOOK FOR ISO SYMBOL MOLDED INTO PART (EXAMPLE: PC + PETP).

3. CLEAN - CLEAN PART WITH SOAP, WATER AND PLASTIC CLEANER (EXAMPLE: DUPONT 2319S OR EQUIVALENT).

4. REPAIR - USING A HOT-AIR WELDER OR A HOT AIR GUN, HEAT DAMAGED AREA VERY SLOWLY FOR MAXIMUM RESULTS. CONTINUE TO APPLY HEAT UNTIL YOU ARE ABLE TO MOVE PART BACK INTO ITS ORIGINAL CONFIGURATION, (NO CREASING OR IRREGULARITIES, AND ALL OF THE MATERIAL IS FLAT). THEN, SHAPE TO ORIGINAL CONTOUR.

5. ALLOW PART TO COOL.

6. REMOUNT THE PART TO THE VEHICLE.
