I have heard different stories. Some say the car comes already with wax on it so you should not wax or polish the first 6 or so months.

Others have said you should do it after the first through wash?

What give with the Altima as I just bought a 2009 3 weeks ago. Also should I just wax or do the whole bit polish and then wax.
