I use Kiwi Mink Oil boot polish which I understand is similar to Imperial. It does work well when I'm only sizing a dozen or so. For more than that I get out the lube pad.
I did see a Youtube video of a guy lubing a large pan of .223 brass with Imperial very quickly. But I'm not sure he got lube on all the cases and he was digging quite a bit out of the can in the process.
