Putting any kind of treatment on the belt or pulley, not specified by the manufacturer, is a momentary fix at best and possibly damaging or dangerous at worst. With the right tools, aligning the belt is a 15 minute exercise so I'd go there first; if you're mechanically inclined, you can do it yourself. The TBird is [in]famous for the chirping belt, although I've only ever had to realign mine once in the last 6 years between tire changes.
