Haven't installed the stove gasket material on my smoker yet, but I found a way to keep the aluminum foil asket I'm using from sliding down the door and hanging up on the top, which eventually comes off when I open and close the door. What an inconvience it has been. Put a little corn syrup on the aluminum foil on the side that would be against the outside of the smoker. It may carmelize but I'm trying it anyway. I'll let you know if it's hard to remove after a smoke. It holds real good.
