First post! I've got three drums with the tan liner in them. I burned two of them for 5 hours filled 1/3 of the way elm. They burned HOT for a solid 5 hours. Paint on the outside turned to pink powder, inside I have patches of bare metal with patches of what looks like remaining carbonized tan liner.
So my question is, should I take it ALL off on the inside, right down to bare metal? I can't seem to get the black patches off, wire wheel isn't doing much.
