Hey gang, so I've been lurking in the background for a few weeks now just trying to read some things. One thing I've read is to seal the smoker with some high temp RTV sealant or Rutland's rope, and then in other posts I also read bah don't worry about it. So based on these particular pictures what would you say? Keep in mind that the exhaust is not wide open. I go back and forth on sealing it or not and using silicone or the rope.
