So I have heard it said a few times people using ptfe plumbers thread tape around plates to seal them. I also use it. I have wondered about the coloured variety for while mainly the pink one cause its thicker, heavier duty. I thought I would share a pic.
It used to all be pink :scared-eek: so I would recomend using only the white tape. This is after two runs. The spirit is now sitting in my cleaner bottle..
