Whatever method you use is just fine as long as you don't stick a case .
The older , STP Oil Treatment type lubes applied with a lube-pad got the job done and will still get the job done when you have a tough re-forming job to do .
There are some cleaner lubes out there .
Lee Case Lube is a water soluable metal forming lubricant that is used in the sheet metal fabrication , door panels , airplane wings ... etc.
being water soluable , it isn't messy , wipes off easily and doesn't contaminate anything it touches .
I mix Lee Case Lube with alcohol , as much as will dissolve , and use a small spray bottle to apply ... spray , roll around , spray ... let dry in 2 minutes and the cases are all lubed . the Lee Lube is dry any remnants wipes off easily ... not messy in the least ... And the stuff is very economical .
Save expensive Ren-Wax for the tough jobs ... the Lee Case Lube works great for all handgun and all but the largest rifle re-sizing jobs ... I had some 303 British that must have been fired in a machine gun chamber ...
I had to break out the Lube Pad and STP Oil Treatment to get them re-sized without sticking a case ...they were a Bear to get re-sized !
