I bought a bottle of this stuff because it was cheaper than the RCBS case lube. Put my brass in a tray, sprayed it down, and let sit for five minutes per the instructions so the alcohol would dissipate off. Started running it through the press, and this shit is horrible. Build up of gunk on the bottom of the die, along with leaving a residue on the cases which just attracted corn cob dust when I tumbled them after sizing. Now I have to go back through and wipe down all the cases. Just a heads up about this stuff.
