So I got all fancy with my new cooker shed/carport and added a chimney and duct. Well, while I was at it, I decided to do a thorough deep clean inside my cooker chamber. Pulled all the parts and pieces out, scraped and vaccuumed. I decided to go ahead and apply a new seal to my lid of the cooker chamber. Scraped the old seal off, wire wheeled the lip & cleaned the lip with alcohol/rag for about 30 minutes. Bought some real expensive high temp from Auto Zone and layed a bead. The first time I applied a seal, I layed the bead around the edge and then applied cooking spray on the outside of the cooking chamber so that when I sat the lid back down on its own weight to "self seal", it wouldnt stick to the other surface. Once done, I used a razor and cleaned up the edges. Worked pretty good since this January! This time I changed it up a bit. I layed a bead of high temp and left the lid open to cure all the way. I thought that since I got lever locks on the bottom of my lid, it would lock it down tight enough to prevent loss of heat/smoke...........not the case fellas. By the naked eye, my surfaces look very straight. My bead does too. Now it releases way more heat and smoke out of the bottom side of the lid. Please enlighten me of ya'lls experiences and methods of correction/enhancement on this process. What did you guys have the best luck with on this issue?
