I am in the process of building my own smoker. Figured I'd give it a whirl after a buddy of mine cooked up some food on his Backwoods Chubby. My question is: Do I need to worry about any sort of coating on the interior of the smoker? High temp paint or any other type of coating? I was just going to leave it raw and sheet the outside and paint the outside of it for looks. Thanks in advance!
