Yes, that makes sense. Sherlock Holmes, now working for the FBI, intercedes. Sorry, I meant the Four –B -I. And what the devil is that, you ask? Simple! Read the fine print at the bottom of the ad. In a phrase that could have been lifted from Mao’s Cultural Revolution, we’re informed that FBI stands for “The Four Basic Improvements.” They are: 1. The aforementioned glass tank, which laughs at rust. Laughs at it! 2. “Absence of dissimilar metals inside the tank!” A more potent ad slogan has never been created, I believe. 3. “Interior tank fittings shielded from electrolytic action, the cause of all corrosion!” Don’t miss Tom Clancy’s next novel, "The Cause of All Corrosion," where Jack Ryan and the FourBI go head to head against the red rust menace. 4. “’Neutralizer’ . . . the anti-corrosion stand-by protector.” Ahhh: 50s technobabble.
