hi folks, just bought a new braunfels sfb smoker off of craigslist for $60 . bottom of the sfb and main body was full of yuky rusty mud. so i shoveled that out and dryed it out. i am in the process of getting all the rust out that i can. my question is when i get to bare metal should i paint the inside with high temp paint or spray it with cooking oil or just start smoking. sorry for no pictures have not figured that out yet. cooking space is 18" x 36" it has little platform on top of the fire box . the wheels seem way to small for its weight. does any body have an idea what model this may be ? thanks for any info.
