I spray it down with "Grilling Oil" after every cook. I am just wondering if exactly what you're saying is the real issue. Can I even get a lasting seasoning in the metal if I am cooking at very high heat almost always.
I guess at this point I just need to super season it the right way like Bluedawg mentions and then try again. If it continues to rust I may have to start thinking of alternatives with a custom cut SS grate or something, which is a real shame because I like my cast iron.
