After a collision, some vehicle structure areas such as frame rails, cross-membersand rocker panel sections may need to be repaired. In most cases, the anti-corrosionmaterials need to be removed to perform these repairs. These materials are classifiedinto two types: Closed Cavity coatings and Undercoat coatings. The primary differenceis the way the products set up or “dry.” Both are intended to protect the surfacethey are appliedto from corrosion caused by water, salt water or Magnesium Chloride blended de-icingcompounds used to thaw icy winter roads. They also can provide a measure of sounddeadening.
The Closed Cavity coatings remain sticky to the touch and will seep into seams initiallyand over extended periods of time. Closed Cavity coatings provide the best corrosionprotection inside of rocker panel sections, pillar sections, frame rails, cross-members,doors, rear compartment lids and closed areas of hoods – anywhere that is concealedor closed off to exterior surfaces.
The Undercoat coatings are “dry to the touch” and offer the best corrosion protectionand sound deadening for floor pans, wheelhouses, inside rear compartment and underhoodareas – anywhere the coated surface is exposed.
Below is a listing of products and coatings that GM believes to be reliable. Whileothers may exist, we have found these products, or equivalents to them, can be usedwith satisfactory results. Always use these products according to their manufacturer’srecommendations.
