So my felt gasket is gone. Lasted all of 2 months. Once the weather warms up, I'll replace it. (My egg now seeps some smoke around a couple edges during a low and slow, and it was a bit more difficult to manage a low temp and keep it stable, so I'm hoping a new gasket will be of some benefit during overnight smokes when constant temp control is critical).
I've researched threads on this forum that suggest making a gasket out of Permatex Ultra-Copper alone. One egger just applied a bead all the way around the bottom, put wax paper on top, and lowered the top. I assume that method would create a nice perfect seal all the way around, and account for any waviness between the top and bottom surfaces.
What is the added benefit of putting the Cotronics or the Rutland on as a fabric gasket (and using the Permatex just as an adhesive)? Is it anything other than just aesthetics at that point?
