If the chassis has rust spots the plating is already gone wherever the rust is, you can't ruin something that isn't there to begin with. Neither Evaporust nor navel jelly (phosphoric acid) will strip the cadmium plating off where it isn't coming off to begin with, you still need to coat it with something afterward, or have it replated.
