I would try 3M Imperial hand glaze, which is first rate. If that doesn't work, clay (with liberal use of detailing spray), followed by a good coat of wax. Since your car is 17 years old, it is also possible that the spots are not directly attributable to Armorall but to other lack of car as well. The 3M product cannot harm your finish, so its worth a try. If you can't find it easily, Pep Boys carries it.
