This is intended to provide general guidelines for urethane adhesive bonding of full panel replacement in regards to collision repair procedures.
Sectioning, partial panel of full panels, is not supported by General Motors unless specifically documented in a Service Bulletin or Manual.
Important:
• Prepare the surfaces to be bonded according to the adhesive manufacturer's recommendations. Many adhesive manufacturers have different preparation methods. Do not intermix adhesive manufacturers systems. Mixing materials from different manufacturers
can produce unsatisfactory results. • DO NOT top coat any adhesive bonding mating surface. Use primer only on bonding surfaces. Refer to adhesive manufacturer's recommendations for priming applications.
