A&J, as I understand it, the polymers in ONR can be painted over. However, I fully agree with you on the whole polymers leaving protection or not. There is confusing messages about it. This is not rare in smaller organisations where communications are often informal whereas in a large organisation the communications will tend to be much more considered but there are many other disadvantages to being a large organisation.
Brad, it took me a while to get used to the idea that ONR would clean and not damage my paint. I would take some reassurance that ONR has been out for over a decade and the forums are not full of people saying their paint is damaged.
I have used the Car Wash (I would call it OCW but this is the same acronym as the wax, OPT need to sort out their naming conventions ) and it is a nice, gentle product and for those who want the traditional approach to washing then the Car Wash is a great product to own. Might be worth considering using the traditional shampoo and alternating with ONR when the paint is not very dirty or just use ONR for the interior or a pre treatment.
I have not tried this with the Car Wash but I have added some ONR to a traditional shampoo to boost lubrication and soften the water. It does work very well but kills most of the suds, maybe it would be worth mixing ONR with the Car Shampoo for when your in the mood for experimentation
