After a collision, some vehicle structure areas such as frame rails, cross-members and rocker panel sections may need to be repaired. In most cases, the anticorrosion materials need to be removed to perform these repairs. These materials are classified into two types: Closed Cavity coatings and Undercoat
coatings. The primary difference is the way the products set up or “dry.” Both are intended to protect the surface they are applied to from corrosion caused by
water, salt water or Magnesium Chloride blended de-icing compounds used to thaw icy winter roads. They also can provide a measure of sound deadening.
The Closed Cavity coatings remain sticky to the touch and will seep into seams initially and over extended periods of time. Closed Cavity coatings provide the
best corrosion protection inside of rocker panel sections, pillar sections, frame rails, cross-members, doors, rear compartment lids and closed areas of hoods
– anywhere that is concealed or closed off to exterior surfaces.
The Undercoat coatings are “dry to the touch” and offer the best corrosion protection and sound deadening for floor pans, wheelhouses, inside rear
compartment and underhood areas – anywhere the coated surface is exposed.
Below is a listing of products and coatings that GM believes to be reliable. While others may exist, we have found these products, or equivalents to them, can
be used with satisfactory results. Always use these products according to their manufacturer’s recommendations.
Prep Treatment and First Stage Coating
In some instances, repairs may be needed for bare metal or minor surface rust conditions. The phosphate treatment and paint listed below are highly
recommended and offer the best corrosion resistance, when applied as a base coat for the Undercoating/Closed Cavity coatings.

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.
