Whether and when to apply CorrosionX or ACF-50 depends on the age of the airplane and where it primarily flies. Over the last 15 years, manufacturing changes have meant that new airplanes come out of the factory with far superior corrosion-resistant treatments than previously. Based on what I learned preparing this article, if your airplane is older than 15 years and it has not had an FTFC treatment in at least five years, it would be wise to seriously consider fogging it at the next annual. Paul New of Tennessee Aircraft Services got my attention when he said bluntly, “If your airplane is 40 years old, it’s corroding.”
