I finished most of the modifications on my new Brinkman Trailmaster smoker. I have one question regarding sealing the smoke/fire chamber. Where the two are connected, I am losing quite a bit of smoke. I have read most of the posts on this thread and wanted to get your opinion. What is your overall consensus on using a high heat resistant RTVV between these two chambers. I don't know how hot the fire chamber gets, so I am hesitant to use the RTV Red that I have on hand. It is rated for 650 degree F "intermittently". I have looked for a higher temperature sealant without any luck. There was one that I found, but someone in a post said that it was not pliable when it set up. Any recommendations? Thanks.
