Ok....Here is where I am at. I have my 300 RF built. I have sanded down the welds on the outside, sanded down the rust spots, and scratches on the tanks. I have not burned it out yet cause the 300 gallon tank was brand new no rust inside, and the 120 gallon fire box was pretty clean in there too. Here is what I am pondering. Should I burn it out before I paint or after. I have 1000 rusteloum high heat paint. I plan on rolling it on, the paint that is left on the smoker now is pretty clean and in good shape. My only fear is the firebox peeling away when I burn in the paint for the first time. I know that the paint on the firebox might stay or might peel away just due to the higher temps and several touchups will probley be in order. Should I burn it in first or just go for it and see what happens and sand it all down later if it looks bad? Thanks for your input.
