I'm pretty anal about keeping my stuff in good shape. I keep a cover on the OKJ when not in use and I powerwash the inside of the smoker every other month or so depending on how often I use it. Recently, I've noticed a bit of rust build up on the SFB and just a small bit on the cooking chamber. While PAM is good on the inside of the cooking area, I'm not so sure it will work on the outside of the SFB or the cooking chamber of the OKJ. I'm hoping someone could point me in the right direction regarding rust prevention. While I realize that there will always be some rust due to the nature of the material involved, there should be some retardant available to slow the process down. Kinda like a cast iron pan I would imagine. Any help would be greatly appreciated !
