I would use good tea bags or even better, loose tea to "boil the hell out of the pot". What you use will impact the flavour for hundreds of cups in the future. Since there's a limited amount of oils per amount of tea/coffee, you might have to do this about five times to get a coating.
That said, with my coffee maker (moka pot), the oils do get an off flavour after a while, so I wipe it with a damp cloth every so often to lessen the oil build up.
I don't know if the coating protects or not, but it sure helps reduce the flavour of the evil metal. It's about the only thing in my kitchen that is aluminum and boy does it make good coffee. I suppose if I could find a copper one, it might be as good, but doubtful. One day I hope to find a stainless steel lined aluminum one.
