I'm going to paste one side of an old strop with cerium oxide and i read the wiki about finishing pastes and it said it was also used as an alterative to jewelers rouge and called opticians rouge,i chose it because it's said to be a very fine smooth polisher and i think it would enhance the highly polished edge my arkansas stones give than coarser or harsher pastes like i used years and years ago but now i'm curious as to how different jewelers rouge is there was a little bit saying it's very similar but slightly faster cutting so i'm hoping someone with more experience can satisfy my curiosity
