Well I've done some of the recommended mods on my 22.5 WSM i.e. mid section handles, lower rack handles, second charcol grate. Now I would like to seal the unit better all around for lower temp capability and more controlled temp over all. What are some on the seal methods people have done to enhance the smoker? I understand there may be a kit I can buy to seal around the door, is there also things people have done to seal around the sections? Other suggestions?
