I don't think I ever showed here on my blog the before and after pictures for my Erika 5 Tab. Not all the blotchy weird stuff on the paint came off with cleaning, it took the rubbing of oil into the paint to bring it back looking great. I'm not sure why oil works so well on washed-out looking black paint, but it does.
