Completed a chore that's been weighing on me for quite some time. Basically replaced the entire inside of my gas grill. The old "stainless" grates were literally falling apart. I bought cast iron grates this time and they needed to be seasoned. They spent several hours oiled and in the oven over the last couple of days. Not the entire time. One hour here and one hour there. In any case, I believe the grill is now ready to be used. Just too tired to do it tonight. TWSS
