Kelbro, I too used Mink Oil for years. Stumbled onto it while looking for an alternative to the gooey RCBS lube. I used to tell guys, do your brass, wipe your fingers on your boots, and when you are done, your boots will be waterproofed as well. But now I use Sizing Die Wax, and its as good, or better, than anything I've ever tried. And modern boots come out of the box waterproofed, so we are all happy.
