Replacement Sheet Metal
Metal or aluminum overlap joints and seams, commonly

hoods, decklids and liftgates should be sealed to

using a quality 2K sealer such as the following
products, or equivalent:

• 3M 8308 Ultrapro sealer or 3M 8323 Factory
Match sealer

• Crest CB-M1 Black Majik or CB-J2 Black Jack
• Kent E-6000 Non-Sag seal sealer
The applied sealer must meet the following criteria:
– The sealer must be free of skips using a ribbon tip to
locate the bead over the edge of the hem. Refer to
the following illustration.

– The sealer must cover all edges with a bead width of
approximately 10 mm (0.39 in) and approximately
2 mm (0.08 in) thick.
– The sealer must be paintable.
– The sealer must retain its flexible characteristics
after curing.
– The sealer must not block a water drain path.
Always use Genuine GM replacement sheet metal.
GM bulletins are intended for use by professional technicians, NOT a "do-it-yourselfer". They are written to inform these
technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper
service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions, and know-how to do a
job properly and safely. If a condition is described, DO NOT assume that the bulletin applies to your vehicle, or that your
vehicle will have that condition. See your GM dealer for information on whether your vehicle may benefit from the
information.
