CONDITION:
Some 1985 thru 1990 Grand Am models and 1988 thru 1990 Grand Prix models may be subject to topcoat delamination after exposure to sunlight and
humidity.
CORRECTION:
1.
Verify that the condition is delamination of topcoat by applying a piece of tape firmly over the suspect area, and pulling upward quickly. If the top
coat and clear coat flake or peel away from the primer, leaving the primer intact, the top coat is delaminating and the following service procedure
should be performed.
2.
Refinish entire body above the body side moldings using the following refinish procedure. It is important that all surfaces above the body side
moldings be refinished, as these surfaces may show the same delamination (peeling) condition at a later time, causing customer comebacks.
It is equally important to remove all glass moldings, body moldings, emblems, door moldings and quarter glass prior to repairs.
3.
Remove 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.
4.
Finish sand exposed Elpo primer with 240 grit sandpaper to assure removal of any chalky residue on the Elpo primer that may remain as a result of
the degradation of the primer.
NOTICE:
DO NOT SAND THROUGH THE ELPO PRIMER TO BARE METAL OR ADDITIONAL METAL PREPARATION WILL BE
REQUIRED TO RESTORE THE ORIGINAL CORROSION PROTECTION.
5.
Remove all dirt from the cracks and surface of vehicle.
6.
Clean sanded surface with grease and wax remover.
7.
Spray entire prepared area with a coat of DP40/401 anti-corrosion primer (PPG/Ditzler) or equivalent. Follow manufacturer's instructions and
recommended dry times.
