I looked at it again -- it's pretty thick, and I decided not to use it.   I bought it to use experiment with as a patch lubricant. Gun slik, huh? I can get that fairly easily, as this is hunting country (only place I've ever worked where most folks in town know where the rifle range is and where even the librarians shoot targets and skeet). I'm currently working on getting the rust off the transformer before I bring it to Sam for work. Some of this stuff is in such shape that I'm embarassed.
