Mixing the abrasives into a paste simply makes it easier to evenly apply.
For the chrome ox you can use GOOP hand cleaner, MInk oil, Neatsfoot oil, jergens hand cream, corn huskers lotion etc. A 50/50 mix is good. try creating one pea sized drop and applying that. let it dry then try it. To much of the paste will actually dull the edge. Less is more.
Hope this helps,
