After bedding in the gasket as per BGE's recommendation it died on my first 600 degF cook! Finished cooking came back to find a funny smell, cooker temp had risen to 750 and the gasket was nuked
All I have left is this
Inside of the the rim is a mess as you can expect, BGE UK have the high temp gasket but you can't get the 3M spray glue in the UK, it doesn't meet out regulations, can't believe it!!!
