OCW has been one of my favorite products. It dropped a couple notches in my book once I got my red HHR because I do experience some streaking with it on that color.
That said, in terms of "looks", I would say that it gives up very little to nothing vs. pretty much any other LSP out there. In other words, I think it looks fantastic.
I've never used it as a stand alone product, but rather to maintain the protection of the base LSP and enhance the appearance.
Looking forward to your results regarding the durability.
