Just joined the Recteq Forum Gang and saw where you made some post about Lava Lock Gasket Seals. I just purchased my first Recteq and chose then Flagship 1100. I would like to add a seal but I had a few questions about Laval Lock. Is there a certain thickness I should use to seal the lid on the 1100 and does Lava Lock gasket seal come in the peel and stick? Thank you in advance for any help
