Adhesive Body Side Moldings

The body side moldings, emblems and name plates are attached to the body panels with adhesive tape. To insure a good replacement of new or old moldings, emblems, and name plates, the panel surface should be warm 21-32°C (70-90°F), clean, and free of any wax or oily film. Methods are listed to attach loose molding ends, completely removed moldings and replacement moldings, emblems, and name plates.

Adhesive Body Side Moldings End Loose

1. Wash the affected area with soap and water and wipe dry. Wipe the panel and the adhesive side of the molding with a clean rag using oil-free naphtha or alcohol.
2. If needed, apply a length of masking tape as a molding guide. A straightedge may also be used.
3. Apply the adhesive to the back of the molding and press in place. If the adhesive GM P/N 1052621 or equivalent is used, apply constant pressure to the molding for 30 seconds or until a firm bond has been made.

Adhesive Body Side Molding Completely Removed

Stripes or Decals

The stripes and decals adhere to a painted surface using pressure sensitive adhesive.

The use of a wetting solution aids the technician in lifting and positioning the stripe or decal during the installation. The wetting solution ensures a better bond between the stripe or decal and the panel assembly. Use a wetting solution when applying large stripe and decal packages.

Complete the following procedures before you apply a stripe or a decal

Scheme 12

1. Metal repair or refinishing after a collision
2. Painting the underlying surface

Maintain a temperature 21-38°C (70-100°F) on the body surfaces and the decals prior to installation. The decal requires auxiliary heat sources in order to warm the body surfaces and decals. If the temperature is below 21°C (70°F) the decal may not adhere to the body surface properly.

Use the wet method in order to apply the stripes or decals that are applied on flexible surfaces (fascias, etc.). This will reduce the formation of bubbles under the decal due to the outgassing potential of the flexible materials.

Use the following equipment and materials in order to apply a stripe or a decal

1. A wetting solution
2. A foaming type of window cleaner that does not contain ammonia.
3. A silicone, wax and grease remover
4. Varnish Makers and Painters (VM&P) naptha
5. Isopropyl alcohol
6. A squeegee 75-100 mm (3-4 in) wide. Made of plastic or hard rubber. Deburr any sharp or rough edges in order to prevent scratching of the stripe or decal.
7. A water bucket and sponge or spray bottle
8. Sandpaper 800 grit or finer Wet or dry type
9. A heat gun J 25070
10. A clean, lint-free wiping cloth
11. A sharp knife or razor blade
12. A pair of scissors
13. A fine pin or needle
14. A marking pencil

Stripe or Decal Removal

1. Remove the following components: Necessary moldings or trim panel Molding attaching clips Handles Sidemarker lamps Other stripe or decal overlapping parts
2. Clean the following areas as needed: The repair surfaces The adjacent panels The openings
3. Use 3M Scotch Brite molding adhesive remover disk 3M P/N 07502 or equivalent in order to remove the stripe or decal from the body panel.
4. Use Varnish Makers and Painters (VM&P) naptha in order to remove all traces of adhesive residue from the painted surfaces.

Stripe or Decal Installation - Wet Method

1. Prepare the surface. IMPORTANT: Remove any imperfections that would appear through the stripe or decal if the area has been refinished.
2. Clean the painted surface using the following types of removers: Silicone Wax Grease
3. Clean the area where the stripe or decal will be applied using a 50-50 mixture of isopropyl alcohol and water.
4. Wipe the panel surface using a clean cloth while the solvent is still wet. Allow the panel surface to dry.
5. Apply the wetting solution to the area where you are installing the stripe or decal. Application of a soapy wetting solution on the top side of the stripe or decal will ease the pull of the squeegee on the stripe or decal and help to eliminate damage. IMPORTANT: Do not touch the adhesive backing of the stripes.
6. Apply the wetting solution on the adhesive side of the stripe or decal. Remove the backing material of the stripe or the decal as needed.
7. Apply the strip or decal to the panel. The wetting solution will allow movement for proper positioning on the panel surface.
8. Working from the center where possible, squeegee the stripe or decal into position. Apply additional wetting solution as needed in order to ease installation.
9. Apply heat to the stripe or decal at the recessed areas. Press the stripe or decal into the recess in order to obtain a firm bond.
10. Use adequate light reflection in order to inspect the stripe or decal from a critical angle. This technique detects any irregularities that may have developed during the installation. IMPORTANT: Do not use a razor blade or a knife edge in order to pierce the air bubbles.
11. Remove all air bubbles by piercing the bubble with one of the following items: A safety pin A needle A tool with a pin size piercing tip
12. Pierce the bubble on the outer edge. Force the air out from the opposite edge using the blade of the squeegee.
13. Install any previously removed components. Clean the components as needed.
