I just got my Oklahoma Joe highland smoker over the weekend and have done two short cooks on it so far. I noticed all the leaks in the firebox and the lids and saw where most people have sealed it rope gaskets and RTV sealant. I'm going to do the same. i was just wondering from those who have done it before, do i need to take the firebox apart to apply the RTV or can i just apply the seal on the outside? any tips would be appreciated.
