I'm making progress on my first build 113 gal propane tank RF. Got the lid cut/mounted and fb opening cut.. Now seems like I should clean/cure or some sort of prep on the inside of the cook chamber before I start on the firebox and rf plate install. I guess wire brushing rust out and all, but what are your recommendations on top of that? Like oiling, burning it out or what not? I know there probably a thread somewhere already, if so maybe someone can put the link? Thanks!
