I just sanded down my strop a bit to remove some nicks, and wish to dress up the leather side with the yellow paste. Before jumping in, I put a tiny dab on the corner of the leather, and noticed it sinks in and dries up very quickly making a dark brown spot. When I try to spread it around (the way I would a diamond paste with the palm of my hand), it doesn't spread at all; and stays concentrated in the area it was applied.

My question - what's the proper way to apply this yellow paste?

Thanks.
