More power to you folks who can ONR without marring. I do use it for some stuff, and I've even recommend it to a few of my pals in the Jag Club. To each their own, glad it works so well for so many people.
One thing I can't figure out is why the wheels I clean with ONR (and then spritz with FK425) are so much harder to subsequently clean compared to wheels I wash conventionally. ONRing wheels between washes is handy, but I do find those wheels to be consistently harder to clean up the next time
