Be careful not to fall into the trap set by the guys who cut and sell those EP stones. They've made a whole market out of talking lots of BS. The thing is that you don't need an EP, nor the expensive special stones they cut, nor special compounds to spray on the special stones when the special stones don't work....it's all a marketing ploy that's being propelled by new/ inexperienced sharpeners or retailers of said products.
So the subject of this thread is about treating strops with compounds, if you're looking for advice on how to treat stones with compounds you'll have to go back to those guys I was just talking about as that sort of crap isn't discussed here.
Sorry to be so blunt but I get riled up when it comes to certain subjects. I mean you (liren1) no ill will. Good luck with your search regardless.
