+ a million on not using too much.
I had an old strop that at one point was more neatsfoot oil than leather, so for years I avoided using it altogether. Recently, I found that a dab of Dovo dressing (in the tiny yellow tube) worked wonders on my latigo. When I say use a small amouont, I mean a small amount. It comes out of the tube about the diameter of the lead from a mechanical pencil, and 1/8" of it is enough. Nothing beats just using a strop until it becomes perfect, but occasionally you need to help things along.
