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.
