You lose the benefit of any natural armor bonus to AC, but the spell grants you a deflection bonus to AC equal to the natural armor bonus you would otherwise have. This deflection bonus does not stack with other deflection bonuses to AC, but unlike a natural armor bonus, it applies to your touch AC as well as your flat-footed AC.
