It is my understanding that ONRWW contains OCW as the wax component. If that is true, then does OCW have a role, if ONRWW is used? If so, what is the role; i.e., when and how should it or could it be used? For example, will it add another layer of wax to provide more protection? How often should it be used? Should it be sprayed on with ONRWW or applied after the car has been washed and dried?
