Well, the alcohol is a diluent and I think of it as the carrier of the lube. When I size the cases they are somewhat wet with the lube/alcohol. I grab a small hand full of cases, spray the lube/alcohol on the cases (while in my left hand), and feed the brass one at a time with my fingers (up from the palm) to the shellholder and operate the press right handed (took a little practice). It works for me and I go pretty fast. I pull the resized/deprimed brass off the shellholder and toss it into a bin. While in the bin, the brass dries and just the lube is left. When I get a tumbler load, I do a final clean and polish.
I like the Lee lube and alcohol mix because it works and is pretty cheap to use. Lately I've taken to using a nitrile glove on my left hand but I've done 1,000's bare handed. I put the lube/alcohol in a 4-5 ounce spray bottle.
