I got a cheap Lowes Perfect Flame vertical propane smoker, and it is working great. The one big problem is that the leaks smoke around the door. I found a local place that had wood stove door gaskets. I picked up several feet, but I have a problem. How do I install the stuff? It is a round fiberglass rope adn the area around my door is smooth. I assume I ned some sort of high heat sealant to act as a glue to hold the gasket rope in place. Anyone have any product recommendations? Thanks in advance.
