This bulletin is being revised to update the models and model years and update the information for Canada. Please discard Corporate Bulletin Number 02-08-48-001A (Section 08 - Body and Accessories).
Effective with the sale of existing stock, General Motors will no longer offer the URETHANE ADHESIVE KIT P/N 12346392 (which includes all associated primers). Until this stock is depleted, the GM kit is still recommended. In Canada, the GM Urethane Adhesive Kit, P/N 10952983, which includes all associated primers, is also being discontinued and will no longer be available after current stock is depleted. It is anticipated that stock will be exhausted no later than May 21, 2006.
As an alternative to the GM Kit for bonded glass installation AND some exterior body panels on specific GM vehicles, various aftermarket materials are recognized as meeting the equivalent of the GM performance specification. This specification (GM 3651G, recently updated) outlines material performance requirements and tests for adhesive manufacturers who develop and manufacture Stationary Glass Urethane adhesives.
Those products currently recognized as meeting those equivalencies are as follows:
^ Dow Automotive (Essex) 400HV (one part and requires associated primers)
^ Dow Automotive (Essex) U216 (two part and requires associated primers) Call Dow Automotive at 1-800-453-3779 for more information.
^ 3M(TM) "Fast Cure" Auto Glass Urethane (one part and requires associated primers) Call 3M(TM) at 1-877-666-2277 for more information.
Any use of these materials should be done as a system by the specific manufacturer. DO NOT intermix primers or adhesives from one manufacturer to another.
