I just recently finished the baffle mod for my Bandera with a piece of scrap sheet metal. Thanks to the print our on the 101 file it turned out great. My question is , after reading other posts I discovered you are not suppose to use galvanized. I have no idea if what I installed is galvanized or not. Is there a way to determine this? I have yet to season the grill so if there is no full proof way of knowing its off to buy a cookie sheet and start over.
