like fastcar said you can never wax too much
and if you wait and wax every two months(personally i dont see that as adaquite), that is not as good as waxing every week. their is never "too much" when it comes to washing and waxing your car. the more you wax the more protection for your paint.
after you wash you should cleaner wax, then polish, then finish with a carnuba wax. if you do that every week it wont hurt the car it will only protect it more, i cant stress that enough
