Review on FireBlack 125: The Ultimate High-Temp Replacement Gasket for Big Green Egg (XL) - Self-Stick Nomex with LavaLock Technology by Brinson Quarterman

Worked like a charm once I figured out how to remove the pad. I was certain it was defective and was ready to call the seller. A notice! Once you have cut a piece, take a small, sharp pocket knife and, starting at the cut end of the liner, slowly separate the edge of the felt from the backing paper. Do not attempt to separate the felt/nomex from the paper or the nomex will tear the paper backing and render it unusable. When you start picking, the paper and Nomex separate, leaving a transparent, thin, glossy adhesive on the block material. At this point, simply peel and stick a few inches at a time, trying not to pull or stretch. big difference This is good stuff!
