I am seasoning my new Old Country Wrangler Smoker today with some lump coal to initiate my fire and some oak splits about 16 inches long and 4 inches wide. I wiped the inside of my pit with canola oil prior to lighting up the fire. Smoke seeped out of the pit door creases and out of the fire box door creases. I plan to seal the doors with Lavalock when it arrives this week! Everything looks great so far. Looking forward to that first cook! Be blessed!
