On a lot full of goodies I picked am old grimy#45 lube sizer. This thing is frozen, whatever passed for lubrication 20 years ago is not doing so hot now. I figure I would shove it in the oven at 200f to help loosen up the died up grease/grime and then start applying WD40 for as long as it needs it. I also figure that while I wait for the WD40 to do its thing that I would ask in case somebody had a better idea.
