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 anti-corrosion 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 Undercoat coatings and Closed Cavity 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.
