I use a hornady lube on the pad, got it from steves wholesalers at the sika show a few years ago just comes in a little clear bottle. I suspect any lube will be fine, I find it a lot easier than rubbing each case. I use the dry lube on the necks too its great stuff. I dry lube 5 cases then roll them on the pad. takes no time at all.
Many ways to skin a cat though. Just experiment and see what works for you.
