There have been occasions where my grill gets caught in the rain. My four year old Akorn 6520 remains too hot to risk covering for as long as 5 hours after cooking on it. I don’t have an overhang to protect it before it cools down. This has happened about twice a year. I do have a bit of rust just above the lower bottom half rim. However it’s mostly on the surface and remains cosmetic for the most part. Of greater concern to me is the water that has filled between the walls of the lower fire bowl. Pretty sure it mostly enters rolling down the bottom rim. Has anyone come up with a solution to prevent water from getting into the fire bowl?
