The most I would feel comfortable using AIO on my car is 6x a year. Thankfully, on a well maintained car, it shouldn't be needed any more than twice a year (i.e. QD every few days or wash every week, etc.etc.).
On that note, I think AIO does a better job of removing micro-marring than any 'pre-wax' cleaner/polish I've tried. It's good stuff... No wonder it has been and will continue to be an extremely popular product on Autopia.
