I purchased mine on Amazon, you will see 99% alcohol and spray bottles purchased together with it.
I agree with using imperial wax for small batches or extreme sizing, but when you are loading a few hundred to a couple thousand the lanolin alcohol mix is the ticket.
I run it at a 12:1 ratio and spray the cases in a shallow cardboard box getting the whole case including the mouth coated with it. let it dry a few minutes and go to town.
I clean it off in the wet tumbler with stainless pins, dawn and lemishine.
There is a large thread on another web site with the title "Case lube for cheap [email protected]" lots of info on making and using it,they claim it is similar to the Dillion spray lube.
