Knows what a fatty is.
I bought a 8 x 24, 16 GA flat stock form Lowes a cut a piece just big enough to cover the charcoal chute. I don't put it on until after warm up and it is time to close the chute door.

This smoker is 4 years old, some moisture will get by the metal.
OK, this is cool. Thanks for posting this - I got it now. I'm going to do the same. Great idea and again, appreciate you sharing!
