Sorry for the late response. With any new Lodge CI, I grind the cooking surface smooth after a hot soapy wash (though the initial wash isn't really necessary considering you're grinding off the surface anyway, but I still do it)....

All of my cast iron has a beautiful dark patina and performs beautifully, whether it's Lodge or not.
Sorry if that answered more than what you asked.
Excellent tutorial Danny, thank you very much! I am going to have to try this.
BTW, what do you grind them down with? I don't own a grinder, so I'm probably going to have to get one. Only a Dremel, and I would assume it would take next to forever with a Dremel tool. <sigh>
