Instead of hijacking another thread I decided to post my own. I am also trying to "seal up" my Chargriller SP. I am not as concerned about the front and back as I dont seem to loose as much heat there. I am concerned about the ends and plan on figuring out another way of getting a better seal there, but I have knocked out the two slots for the rotisserie for Pheasants we do in the winter. Right now I have balled up flat pieces of foil that I have jammed into these slots and believe it's working fairly well. Does anyone have any recommendations or has any one hurdled this problem yet? Thanks for reading and any advise.
