Well, after last nights cook, I open the lid and the left side bottom gasket lifted. I then pulled it straight off with no problems! Went to the store and got the 3M 77 but before I put gasket back on, I took this time to make sure the top was perfectly flat against the ceramic. Yes, I had to adjust the bands! When it was 'perfect, I put the gasket on some paper, sprayed it and put it on in about 45 seconds. Pushed down and got wax paper between the dome and closed.
We will see...
