# PROTECTIVE BARRIER COATING MATERIAL REMOVAL PROCEDURE

A protective milky, wax-like paint coating is being applied to the top surfaces of some 1989 models. A pint container of concentrated detergent remover will be shipped loose in each vehicle and must be used in a diluted solution to remove this coating.

This material is exactly the same as referred to in bulletin 88-SM-7 used on 1988 and 1989 Grand Prixs and will be introduced on other Pontiac models this year.

Since the remover will be shipped loose in the vehicle, it is important to note any shortage on the Transportation Delivery Receipt. If a damaged or missing container is noted, replacement may be ordered directly from the supplier:

Hanson-Loran Chemical Company, Inc. 6700 Caballero Blvd. Buena Park, CA 90620 714-522-2201

The use of the supplied remover is a direct replacement for the normal new vehicle wash; therefore, the time allowance for New Vehicle Inspection is unchanged. Complete environmental information may be obtained by contacting the supplier.

Refer to bulletin 88-SM-7 for the material Safety Data Sheet.

Following are helpful instructions when using the remover and environmental information for your files.

GENERAL MOTORS TRANSIT COATING REMOVER

Additional dealer instructions for the removal of the transit coat are as follows:

The instructions on the bottle of remover must be followed exactly in order to successfully remove the coating. Whether applying the remover by hand or by spray, a very wet lather (suds) must be produced and allowed to remain wet and in contact with the coating for a minimum of 40-60 seconds. If the remover is not well lathered or dries on the coating, the removal process must be repeated in full. A complete rinse is then required.

To insure ease of removal, the coating must be removed from vehicles no later than 4 months after receipt of the vehicle by the dealer.

Coated vehicles with excessive dirt or with any visual etch should be rinsed well by the dealer upon receipt of the vehicle. If contaminants or any evidence of etch remains after rinsing, the coating should be removed immediately so that the contaminants will not have sufficient time to fully penetrate the coating and reach the paint surface. If the coating surface appears to be clean and unbroken, the coating can be left on the vehicle in the lot for up to 4 months. All vehicles should be rinsed before removal of the coating to avoid scratching the paint surface.

Coated areas of the vehicle which may need special attention during removal include windows, wiper arms and blades, window molding, horizontal areas of bumpers/fascias, tires, wheel covers, door handles, and trim. There have been reports of clogged windshield wiper mist holes due to the coating remaining on wiper arms.

This information should assist in a more effective removal of the coating.

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.
