When foiling the top of the woodbox, should the foil be wrapped tight over all four edges, and if so, is it better to do the ends or sides first? Or should the foil be "loose" with just an edge slighty folded over to keep it in place? I keep getting grease & etc seeping back under the foil which burns onto woodbox and "glues" the foil to the top of it. Yes, I do use the Extra Heavy Duty foil, and I know NOT to block the smoke outlet holes on side of woodbox. I would appreciate any little foiling tricks you seasoned users have. Thanks!
