Info - Application of Anti-Corrosion Materials

This bulletin is being revised to add model years and the HUMMER model. Please discard Corporate Bulletin Number 01-08-51-003 (Section 08 - Body and Accessories).

After a collision, some vehicle components, such as rocker boxes or frame rails, may need to be repaired. In some cases, the removal of the anti-corrosion materials is necessary. These materials are classified as interior and exterior protectants. After extensive testing to the GMP9540P corrosion specification, which included the evaluation of 16 different products and 135 plaques, the following products have been selected to be used when repairing General Motors vehicles.

For interior application, a specially designed gun and wand must be used in order to perform a quality repair. These products are available as a kit through GM Dealer Equipment at 1-800-GM-TOOLS (1-800-468-6657) (Press 2 for supplies). For technical information, call 187-Permatex (1-877-376-2839), (in Canada, 1-800-924-6994). The exterior products are available in aerosol cans or quart cans. The application of the exterior protectant is done in the typical manner.
