1989 CADILLAC PAINT INFORMATION

VEHICLES AFFECTED: 1989 C,D,E,K,V SERIES

The listings of 1989 paint codes contained in this bulletin will enable Dealers to order the necessary paint materials required for effective field repairs.

The list of colours indicates the suppliers' ordering codes for exterior, interior, vinyl roof mouldings, and paint stripe colours. Listed below are Cadillac Assembly Plants and their suppliers. It should be noted, however, that paint suppliers are subject to change.

Assembly Plant Paint Type Paint Supplier Paint Codes -------------- ---------- -------------- ----------- Hamtramck Clearcoat Enamel DuPont All Hamtramck (Allante) Clearcoat Enamel PPG All Orion Clearcoat Enamel PPG All Arlington Dispersion Lacquer DuPont All

Other manufacturers produce service paint which could perform satisfactorily for field repairs. Paint suppliers in your area can provide you with information regarding these materials.

The paint listed in this bulletin is (or soon will be) available from local paint suppliers.

The Service Parts Identification (SPID) label illustrated in Figure 1 is located on the inside of the trunk panel or the spare tire cover. This label contains the paint codes needed to identify the paint materials for field repairs. Note this label identifies the paint code along with the WA# for that paint code. It is equally important to use this WA# along with the paint code to identify the correct repair materials. This is especially true for codes #17 Pearl Gray and #50 Flax, where the WA# identifies the clearcoat repair material from the dispersion lacquer repair material. Care should be taken to transfer the SPID label or its information if the panel to which the label is affixed requires replacement. Replacement SPID labels are not available.

EXTERIOR PLASTIC PARTS

All 1989 Cadillacs have exterior parts made of various types of plastic materials that require specific procedures to obtain high quality refinishing results. Included in this bulletin is a chart listing the different types of plastic materials used on 1989 models. For best results when painting is required, determine the type of plastic material from the chart. Then follow the correct paint procedure, depending upon what painting material and equipment is available.

There are a multitude of finishing systems available on the market for painting and/or repairing flexible plastic parts. Following is a general outline of painting procedures, includinga list of available products. Refer to the manufacturer's literature available through your jobber for details on proper mixing and application.

1. Thoroughly clean part by washing with a suitable cleaning solvent* to remove all surface contaminates.

NOTICE: Previously parts that shown signs of cracking, peeling or improper adhesion must be stripped before repainting. The old finish may be removed with any commercially available chlorinated solvent stripper or lacquer thinner.

NOTICE: Do not soak parts longer than necessary to remove the old paint to avoid swelling.

2. Scuff sand to an even dull appearance the entire surface to be painted with fine (400 grit) sandpaper and feather edge any damaged areas and rewash.

3. Apply two (2) thin coats of primer when required per top coat manufacturer's recommendation and allow to completely dry before proceeding. (For most products, approximately 30 minutes).

4. Prepare colour coat according to the manufacturer's recommendation and apply sufficient double coats to develop the proper shade. For best results, allow a few minutes flash time between each double coat and allow to completely dry before using.

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. See a General Motors dealer servicing your brand of General Motors vehicle for information on whether your vehicle may benefit from the information.
