RE: [FOT] liner coatings update

 wow, what a pain. I can't imagine that will be any good for heat transfer
either. I clean my sleeves to bare metal before assembly and try to avoid
touching the side with my greasy paws.

If nothing else works you probably could get them soda blasted. I'd use
glass bead blasting before I'd put in sleeves with some kind of gunk on
them.
