so i bought a strip of latigo leather from a local saddle maker today and we got talking about shaving with a SR. he said that uses jewelers rouge, either the white or red, for certain leather tools he has. he said it really makes a huge difference on these fine, sharp tools and he gave me a chunk to try. i have seen jewelers rouge mentioned before but have no idea where in my progression it would best fit.

i have a CrOx strop that i really like, but how would i know if it is finer?
it reminds me of buffing compound, so what is the easiest way to use this stuff?
i was thinking of putting it on the backside of my linen, good choice?

thanks
Wes
