Model and Year: 1988-89 CHEVROLET S/T PICKUPS AND S/T BLAZERS (SHREVEPORT ASSEMBLY PLANT ONLY - PLANT CODE "8")

TO: ALL CHEVROLET DEALERS

THIS BULLETIN CANCELS AND SUPERSEDES DEALER SERVICE BULLETIN NO. 89-305-10, DATED APRIL 1990. ALL COPIES OF 89-305-10 SHOULD BE DISCARDED AS THIS BULLETIN CONTAINS AN EXPANDED SERVICE PROCEDURE.

General Motors has determined that some 1988-89 Chevrolet S/T pickups and S/T Blazers built at the Shreveport Assembly Plant may exhibit a delamination (peeling) of the paint on exterior surfaces due to continued ultraviolet exposure. If one of these vehicles should require repairs for a paint peeling condition, all exterior surfaces painted with affected colors should be refinished even though the peeling may be evident in only a few places.

VEHICLES INVOLVED

Involved are certain 1988-89 Chevrolet S/T model trucks painted Galaxy Blue (paint code 28), Aspen Blue (paint code 24) or Steel Gray (paint code 90) and built at the Shreveport Assembly Plant within the following VIN breakpoints:

MODEL YEAR PLANT FROM THROUGH ----- ---- ------- ------- -------- S/T 1988 Shreveport J81 73137 J8243291

S/T 1989 Shreveport K8100001 K8256108

SPECIAL POLICY ADJUSTMENT

This special policy covers the condition described above on 1988 involved vehicles for 12 months from the date of this bulletin. 1989 involved vehicles will be covered for a period of 3 years from the date of original vehicle purchase regardless of ownership with no deductible. Correction, at no charge to the customer, will consist of refinishing exterior surfaces painted with affected colors on involved vehicles. Customers may also be eligible for reimbursement of previous repairs with supporting documentation.

NOTICE: Only exterior surface areas painted Galaxy Blue, Aspen Blue or Steel Gray should be refinished. If peeling of colors other than those described above should occur, handle as described in the Chevrolet Claims Processing Manual, Section XIII, Warranty Management System. This "Special Policy Adjustment Bulletin" should be filed in the three ring binder previously furnished to dealers by General Motors.

PARTS INFORMATION

No parts are required to complete this special policy. Paint supplies should be obtained through normal supplier.

SERVICE PROCEDURE

1. After washing vehicle, verify that condition is delamination of topcoat by applying a 2 inch width piece of masking tape firmly over suspect area, pulling upward quickly. If topcoat and/or clear coat flake or peel away from primer, leaving primer intact, the topcoat is delaminating and the following service procedure should be performed.

NOTICE: For two tone vehicles, it is only necessary to refinish surfaces painted Galaxy Blue, Aspen Blue or Steel Gray. Other colors should not be affected by this condition. The front bumper filler panel and all surfaces painted with affected colors above the belt line (Fig. 1, page 3) must be refinished according to the procedure listed below (regardless of previous paint repairs). If surfaces below the belt line and the interior of the pickup box (on pickup models) appear to be in good condition, the dealer should scuff sand, seal and color coat those painted surfaces rather than refinish. However, if any peeling or topcoat delamination is evident, or if scuff sanding produces any topcoat delamination, it will be necessary to refinish these surfaces as well, according to the procedures. It should not be necessary to paint inside of door jambs, or underneath exterior moldings or decals (sunshine stripes), as these areas are not normally subjected to continued ultraviolet exposure.

2. Sand original finish coat of paint down to electro-coat (Elpo) primer, making sure factory pretreatment and Elpo primer are still intact for good corrosion protection. DO NOT USE CHEMICALS TO REMOVE PAINT AS THIS MAY DAMAGE THE ELPO PRIMER.

NOTICE: Rough tape vehicle as necessary (window glass, etc.), and remove nameplates, weatherstrips, and reveal moldings as needed to properly refinish all surfaces as required.

3. Finish sand exposed Elpo primer with 240 grit sandpaper to assure removal of any chalky residue or degraded Elpo primer that may remain as a result of overbaking the primer.

NOTICE: Avoid sanding through Elpo to bare metal when possible.

4. Use an air gun to remove all dirt from cracks and surfaces of truck.

5. Clean sanded surfaces with grease and wax remover.

6. Spray entire prepared area with a coat of DP40/DP401 anti-corrosion primer (PPG/ Ditzler) or equivalent. Follow manufacturers instructions and recommended dry times.

7. Apply 2 to 3 medium wet coats of primer-surfacer to primed surfaces of truck, making sure to follow manufacturers instructions for application.

8. After allowing adequate drying time, wet sand with 400 grit (or finer) sandpaper or dry sand with 320 grit (or finer) sandpaper.

9. Repeat steps 4 and 5.

10. Apply 1 medium wet coat of primer sealer, following manufacturers instructions.

11. Apply 3 to 4 medium wet coats (or until primer color is well hidden) of Acrylic/Urethane Enamel Color. Follow manufacturers instructions.

NOTICE: Reinstall all trim and other items removed in step 2.

12. Final wash and detail vehicle.

General Motors bulletins are intended for use by professional technicians, not a "do-it-yourselfer". They are written to inform those technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions and know-how to do a job properly and safely. If a condition is described, do not assume that the bulletin applies to your vehicle, or that your vehicle will have that condition.
