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, and pulling upward quickly. If top coat and/or clear coat flake or peel away from primer, leaving primer intact, the top coat is delaminating and the following service procedure should be performed.
2. Refinish all horizontal surfaces (regardless of previous paint repairs), including hood, deck lid (remove luggage rack if so equipped) and roof using the following refinishing procedure. It is important that all horizontal surfaces be refinished, as other horizontal surfaces may show the same delamination (peeling) condition at a later time, causing customer comebacks. Blend fenders, quarter panels and sail panels.
NOTICE: Rough tape vehicle as necessary (rear window glass, headlamp areas, fenders, etc.) and remove nameplate, weatherstrips, weld joint seals, emblems and reveal mouldings to properly refinish all horizontal surfaces.
3. Sand original finish coat of paint down to electro-coat (Elpo) primer, making sure that 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.

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.
