Automotive corrosion enhanced by deicing salts has been recognized for years as a major problem in reducing the useful life of cars especially in Northeastern United States and the bordering regions of Canada. 1  In combating the increased corrosiveness brought out by greater usage of deicing salts automotive companies and individual car owners have placed most of the emphasis of protecting the body panels to prevent or at least to delay metal perforation from corrosion. The methods currently in use are "rustproofing" the car by spray coating critical internal areas of body panels after the car is assembled or by affording corrosion protection to the inside of the panel by means of coatings applied to the flat sheet prior to forming (e.g., Zincrometal* or various types of one side galvanized products). While these methods are providing relief to the rapid deterioration of body panels, little progress has been made in providing equivalent corrosion protection to underbody structural members.
