dougcrann Hi Doug, I know I'm late chiming in with my 2 cents, but I'll add it anyway.
I add the rub and then dust the thick skin side with cornstarch. I use a small strainer and tap it on like I am adding powdered sugar to the top of a cake. I will then put them in the refrigerator while I get the BGE to temp. I cook chicken wings raised direct at 325F for about an hour and 15 minutes. I cook them thick skin side up for about 45 minutes and then flip for the rest of the cook. There are many ways to cook great wings on the BGE... this is what I found works best for me. Good luck!
