Maybe you should try stuff before commenting against it ...
I have not used ONR in a spray bottle yet but I don't see why it wouldn't work like S&W. I do wonder what will happen using it at a stronger dilution than in a wash bucket. Will it be detrimental to the LSP?? There really isn't much of difference between ONR in a bucket or in a spray bottle, IMO. As long as you keep your towels clean, I don't foresee it marring.
Poorboy's Spray and Wipe is a great product. It acts like a QD but has great cleaning abilities. I'm no scientist but after using it, I can tell you that the dirt gets encapsulated by the product and when wiped, not rubbed, off it is safely removed from the paint with a clean microfiber towel. No marring. Using 1 MF towel when folded you can get 8 clean parts of the towel which could be used on 1/2 the car, in the right conditions. The dirtier the car, the more product and more towels are needed. Using a traditional wash, dirt is still rubbed into the paint by whatever washing tool you use. If that tool is abrasive, it will marr the paint. A MF towel, as everyone knows, is very soft and safe on paints. Using a long knap towel for S&W will further reduce the risk of marring with S&W. It is possible to marr with S&W but that is generally only because there wasn't enough product used, the MF towel is dirty or if the paint is rubbed not wiped (be gentle). If you don't want to take my word for the safeness and effectiveness of this product, check out these picturs from blkyukon - A dirty black Chevy, under halogens, cleaning with S&W:
And to comment about using CG One vs. S&W... CG One has fillers and clay in it... so if the product were inducing marring, you wouldn't know it until the product wears off. If I made a mistake and accidently marred with a waterless wash, I would like to know about it ... not hide it. S&W is a pure cleaner, no protection or clay or whatever.
