PAINT DAMAGE TO AERO MOLDINGS (PREPARE/APPLY SHIELDS)

SUBJECT: PAINT DAMAGE TO AERO MOULDINGS (PREPARE/APPLY SHIELDS)

VEHICLES AFFECTED: 1989-93 "W" COUPES WITH B4U OPTION

APPLICATION:

----------- 1989-1993 Pontiac Grand Prix Coupes With B4U Option

Some owners of 1989-93 W cars who travel unpaved or gravel strewn roads may comment on paint damage to aero mouldings due to stone impingement.

This bulletin is being published to outline a procedure to protect these surfaces with transparent chip resistant shields.

NOTE: Before application of protective film, the damaged areas must be repaired and refinished as necessary. Otherwise, film will not adhere or be cosmetically acceptable. Apply shields to all areas shown in Figure 1.

PREPARE SHIELD TEMPLATES:

1. Cut-out templates from pattern sheet (Figure 2)

NOTICE: Use the reverse side of the templates for the opposite side of the vehicle.

PREPARE PROTECTIVE SHIELDS:

1. Place each template on the clear protective film (3M P/N 06448 High Performance Film or equivalent) with respect to the desired side of the vehicle.

2. Trace around the templates, then, cut out shields using a sharp blade or scissors.

CLEAN SURFACES (Figure 1)

1. Indicated areas of lower bodyside mouldings. Use a lint-free cloth soaked in a solution of mild liquid detergent and water.

2. Rinse with clear water. Wipe dry with lint-free cloth.

3. Indicated areas with a lint-free cloth moistened with isopropyl alcohol. Let dry.

APPLY SHIELDS:

1. Peel the protective backing from the film.

2. Apply (spray or wipe with a lint-free cloth) a solution of 25 percent isopropyl alcohol and 75 percent water to affected area.

NOTICE: 3M recommends using alcohol and water. If an equivalent film is used, check manufacturer's directions.

3. Wipe or spray the affected area again if it has dried, as the solution provides lubricity for the patch to allow movement before final placement. Observing locating directions on the template, apply each shield to it's respective area. (Figure 1)

4. Using your fingers or a small decal applicator (squeegee), work out bubbles and the alcohol/water solution.

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.
