I found an unopened pkg of Otis Lifeliner that I forgot I had bought (+-$100 w/shipping) a long time ago. I"ve looked at old posts on line, seen it called BS, snake oil, etc. I remember when "Teflon", micro-lubes, synthetic oils were new and treated the same way. I haven't seen any posts that claim to have used it themselves.It's no longer listed on the "Otis" site, got to call them. Anyone have or know someone has used it?? Thanks, Paul
