This may be a dumb question, but how long do you wait to apply a wax after you have applied and wiped off the polish (or do you even have to wait?). I will be applying Meguiar's Deep Crystal Polish under the NXT wax (per a Meguiar's rep's instructions), but as a novice to car cleaning, I'm unsure whether there is a curing period for polishes like there is for waxes.
