I tried Optimum No Rinse when I first got my car, and found it was causing a lot of fine scratches. I blame this more on the very soft finish of the car than on the ONR, but I switched and had my car coated in C. Quartz Finest, and now I'm happy.
Yes, thing to remember is that cars with the good nano coats will be MUCH easier to keep clean, requiring less abrasion. Also, product like ONR is not waterless, it's rinseless. The waterless washes are pre-mixed dilution for more lubricity. For ONR, most people will want to do a traditional pre-rinse to knock big stuff off the car prior to the actual wash. Difference is there is no final rinse there.
I'll share a safety tip about true waterless wash from personal experience. Watch out for ones with strong colors. I didn't see the one mentioned here but I had tried one early on that had orange color. Ended up with some light staining in clear. I may have left it on surface too long and thankfully only limited spot cleaning, not the whole car. You have to be certain to get the product off the paint or you may have problems because those pre-mixed waterless washes are more concentrated for the higher lubricity. I have never had problem since switching to ONR and ONRWW. You can theoretically alter dilution on it to be more like QD or clay bar lube too. I'm not saying there will be problems with EVERY true waterless but watch out.
And yes, I also generally find it requires a lot of caution to avoid the micro scratches no mater which wash solutions you are using. With a rinseless, like ONR, I think the trick other than using high quality wash media, is to rinse it OFTEN throughout the process and never put it back into the clean wash solution. Either blast it out occasionally with hose nozzle in between washing sections (or similarly use the multiple bucket method).
Moe Mistry also posted a wash method post somewhere recently here. Ok, it's under the thread "tesla paint issues and coatings" that was started by a pro detailer explaining how TM is getting bad rap from some and paint issues are not as severe as some people claim they are.

Never to the car Wash. Zaino only. Cotton towels. By hand, no tools, but I might get that wheel brush because the lug nuts are so time consuming
I looked at so many wheel brushes but I have the 19" where you have to get way into the barrels to clean them or they look like heck. I have been too chicken to try wheel brushes because of the handles scraping the outer parts when you try to get in far enough to clean.
I am also a little chicken to use very caustic chemicals and try to go for green solutions. Those solutions are not the easiest to find for sure. It can take quite a time investment. Probably another good argument for getting a good coating on your car to make it easier to clean. As a frog once said "it aint easy being green". I usually don't use any product if I haven't been able to review the MSDS and satisfy myself it doesn't have too much scary stuff in it for long term enviro effects (one of the reasons I landed on many of the Optimum products although they are not the only ones for sure and there are probably more options even now).
BareyB was also asking for advice on leather cleaning. I have textile interior. Anybody have advise for him? I've seen many recommendations about that as well. Supposedly you can use Optimum Protectant Plus at dilution ratio on leather as well as vinyl and plastic trim. Others like products like Leatherique? I cannot make a strong recommendation for him at this point.
I have to say that being a relatively short woman, getting some of the microfiber "wand extension" type products has generally helped me to reach into the center of this big, wide car (roof, hood) without killing myself and without damaging the car. There are also some microfiber products designed specifically to clean the inside of the windshield which can be quite difficult. I'll try to find some examples and post.

If you polish your wheels with Zaino as well you may never need separate tire cleaner. ...
Good advice because the wheels have clear coat and protecting them with good nano coat is same as protecting paint, making it so much easier to keep clean without all the caustic chemicals.
