I've been trailing various products
ONR is superb and when used with a GOOD microfibre pile does a great job at 8/1 ratio
I find even a few splashes with a normal wash (Using wash mitts) really brings the car up well ... ONR gets my vote, but dwell time is key and car can't be caked in crap.
Also tried No2h20 - it's just a detailing spray at best..over priced Tat .
Tango by Autosmart is a nice bridge between light waterless wash and good detailing spray.
I use Pink Stuff for the wheels which is non acidic..it's great think it's called Berry Cherry or something
I'm no professional and the thread on here for coupe detailing is,awesome..but as it's written by pros..I assume They'd pahpah waterless or no rinse products
