Some of the above subject vehicles may experience loss of paint adhesion on instrument panels. The loss of paint adhesion can occur as a result of a
combination of certain types of cleaning compounds applied to the instrument panel after painting and the combination of sunlight and high interior
temperatures.
Certain cleaning chemicals can result in negative effects on the instrument panel (I/P) and can cause the paint to peel. The I/P should be cleaned with
soap and water ONLY. Products containing the following chemicals should NOT be used to clean the I/P:
*
Acetone
*
Alcohols
*
Aliphatic Hydrocarbons
*
Aromatic Hydrocarbons
*
Esters
*
Ethylene Chloride
*
Ketones
*
Methylene Chloride
*
Napthas
*
Penetrating Oils
*
Plasticizers
*
Propylene Glycols
*
Silicones
*
Tetrachloroethane
Some after market products used to increase the gloss of the I/P contain some of the products listed above. It is important to use only those solutions
recommended for cleaning the identified surfaces. As a general rule, the following guidelines can be used:
*
Vinyl and Non-painted Plastic - Use vinyl and plastic cleaners.
*
Rubber - Use rubber cleaners.
*
Painted Plastic Surfaces - Use only mild detergents.

SUBJECT:
HOOD PAINT FLAKING
MODELS:
1989 C/K 1, 2, 3
Hood paint flaking or adhesion may be experienced on some 1989 C/K trucks within the breakpoints listed. This condition was caused by an improper
galvanizing process. The flaking condition to bare metal will be most noticeable on the edges of the hood. Hoods that were built within the suspect time
period may be identified by the number 39 stamped in the right edge approximately 16 inches from the front of the hood. If paint flaking occurs on a
hood with a number 39 stamped in the right edge and the VIN is within the breakpoints listed, the hood must be replaced and refinished. Do not attempt
to refinish the original hood. Order Hood P/N 15611248. Parts are currently available from GMSPO.
