Jason, you've caught some of the early website text that needs a little, uh, "freshening" (to put it nicely). No foil required on the seasoning run, just when cooking. I don't recommend foil for 2 reasons. First, what is stated here about burning off the factory oil (it kind of stinks). Also, the smokers are made of "stainless" steel, not "stainproof" steel. I think a good coat of smoke helps protect the surface of the metal. While the stainless used in these smokers is very resistant to rust and corrosion, a little extra protection never hurts!
