I mixed up a batch with 1/3 bear oil, 1/3 crisco, 1/3 wonder lube. Mixed it all up and melted it in microwave, then mixed in a tub of JB Bore cleaner thinking that the ultra fine silica grit in the JB would polish the bore every shot. I dont really know if it worked that way as the bores didnt look any different when I eventuly ran out of the stuff, but it did work ok as a patch lube with no unusual fouling. Gary
