2. Apply GM-approved Weld-Thru Coating or equivalent to all mating surfaces. Refer to «ANTI-CORROSION TREATMENT AND REPAIR»(/buick/regal/v-2009-2013/remont/paintcoatings/#paint-and-coatings__anti-corrosion-treatment-and-repair)
3. Position the rear rail-rear section (1) to the vehicle using 3-dimensional measuring equipment. Clamp the rear rail lower into place.
4. Plug weld accordingly (1).
5. Clean and prepare all welded surfaces.
6. Apply the sealers and anti-corrosion materials to the repair area, as necessary. Refer to «ANTI-CORROSION TREATMENT AND REPAIR»(/buick/regal/v-2009-2013/remont/paintcoatings/#paint-and-coatings__anti-corrosion-treatment-and-repair)
7. Paint the repair area. Refer to «BASECOAT/CLEARCOAT PAINT SYSTEMS»(/buick/regal/v-2009-2013/remont/paintcoatings/#paint-and-coatings__basecoatclearcoat-paint-systems)
8. Install all of the related panels and components
9. Enable the SIR system. Refer to «SIR Disabling and Enabling»(/buick/regal/v-2009-2013/remont/airbag/#supplemental-inflatable-restraint-system__sir-disabling-and-enabling) .

Note. The use of heat to repair damage is not recommended for this classification of steel.

Recommended Repairs

1. Cold repairs can be performed on this type of steel, unless the damage includes kinks. If the damage includes kinks, the part should be replaced.
2. Sectioning or partial replacement of this type of steel is recommended only at approved locations, in a specific sectioning procedure.
3. This type of steel can be used as a sleeve, or backer plate, when recommended in a specific sectioning procedure.
4. Squeeze Resistance Spot Welding can be used to replace factory spot welds, where applicable.
5. MIG plug welding and MIG stitch welding can be used on this type of steel.
6. MIG Brazing can be used on this type of steel.

High Strength Low Alloy Steel

This information provides repair recommendations and general guidelines for steel classified as High Strength Low Alloy Steel, also known as HSLA. This type of steel normally has a tensile strength range from 300-700 MPa.

General Motors recommends the following when repairing or replacing this type of steel during collision repair.

Recommended Repairs

1. Cold repairs can be performed on this type of steel, unless the damage includes kinks. If the damage includes kinks, the part should be replaced.
2. Controlled use of heat can be used to repair damage, if the heat does not exceed 650°C (1200°F). The heat should be applied a maximum of 2 times, for up to 90 seconds.
3. Sectioning or partial replacement of this type of steel is recommended only at approved locations, in a specific sectioning procedure.
4. This type of steel can be used as a sleeve, or backer plate, during sectioning procedures.
5. Squeeze Resistance Spot Welding can be used to replace factory spot welds, where applicable.

Metal Panel Bonding

This is intended to provide general guidelines for adhesive bonding of exterior panels as an alternative to Metal-Inert Gas (MIG) welding. Panel bonding may be seen as an alternative to MIG welding to provide full panel replacement in regards to collision repair procedures. The benefits of panel bonding is

1. No heat or burn damage when additional welding is not required
2. Corrosion protection
3. Can act as a sealant
4. Improved process for complicated shapes (wheelhouse area)

The General Motors specification for metal bonding adhesives is GM 6449G. The scope of this specification is intended to provide the performance guidelines of structural adhesive systems used to repair (metallic) automotive bodies in the aftermarket. These types of adhesives are intended for use when bonding replacement body panels as an option to welding as the attachment means. GM information outlines the use of room temperature cure acrylic adhesives that contain glass bead technology.

Bonding procedures in general are applicable only to a factory seams type approach.

Sectioning or partial paneling of full panels is not supported by General Motors unless specifically documented in a Service Bulletin or Manual.

Applicable components for this technology are EXTERIOR PANELS ONLY, including door skins, tail panels, roof outer panels and quarter panels.

Adhesives currently meeting the performance requirements include General Motors materials and products manufactured by Lord Adhesives. At this time, ONLY the adhesive products listed below meet this guideline
