This study was concerned primarily with a laboratory evaluation of the effectiveness of several chemical inhibitors in reducing corrosion of autobody steel by deicing salts. Under the controlled exposure conditions imposed in the laboratory tests, the treated salts appear to be quite effective in reducing corrosion. It was therefore deemed necessary to further evaluate the effectiveness of anticorrosive salt under natural conditions of exposure more typical of that experienced by vehicles in normal use.
A separate field evaluation was conducted beginning in the fall of 1965 and continuing through the 1966-67 winter. The results of this study, in comparison with the results of the laboratory study indicate a much reduced effectiveness. Because of the difference in the findings of the two studies, a summary of the final report of the field evaluation is given in Appendix C of this publication.
