Hello. Welcome. I see this is your first post. Please take some time and swing over to Roll Call and introduce yourself so that we may give you a proper "Hello". All info you can provide us with such as smoker type, location and so on will help us answer any questions you may have. As for your question: Here is my opinion for what it is worth. Others will have different advice. This is only my opinion. This is posted in UDS builds and would have a better chance in Smoke Houses, hopefully a moderator will move it. I would leave the inside bare and let the smoke do it's thing. The longer you use it the better it will get. Keep Smokin!
