I just had my first experience with ONR and the BRS!
The car was not that dirty, just some light dust, a couple of bird bombs and dirt in some areas. I did a light pre-soak with the ONR solution and then proceeded to use the BRS. At no point did I feel it was doing any damage and it was definitely much quicker and more enjoyable than my previous multiple towels rinsless wash technique.
In certain areas, I did pick up a little dirt on my drying towel but I wasn't too worried about that. I think it will just take some time to get used to this new process and I'll have to go over some areas a couple more times with the BRS where needed.
This ticks all the boxes for me and overall I'm really impressed.
