1. Visually inspect the front right and left roof laser
braze, then the rear right and left roof laser braze,
for pin holes or a crack.
2. Seal the holes/crack in any laser braze area

Seam Sealer Clear P10200, or Wurth
Euroseal Gel Clear 18920104, or equivalent

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.
