Have a look at this thread I authored last year -
DFB's Rinse-less Wash Shootout
While I have been detailing cars in some form or another since I was all of 14 years old, so about 24 years, I’m relatively new to rinse-less and waterless washing. In terms of water-less, I’m only using that method on door jambs and engine bays, but rinse-less is now an important part of my detailing skill set.
What I love about rinse-less wash products is the versatility. In addition to rinse-less washing, I’m using these products as a quick detailer, waterless washing of door jambs and...
I've tended to like the polymer type, they feel more lubricated, which I felt important coming from being a heavy soap user. I really like ONR and Absolute for that reason. I think the polymer type are a nice balance between the products laced with wax or Si02 (which can be fun), and the surfactant-based options that are said to "leave nothing behind". The reality is, any rinse-less will leave something behind, even the surfactant ones, so I guess it comes down to how much you want left behind. Personally, I've never really cared about the "nothing left behind" thing.
At the moment, I'm gravitating towards the following -
P&S Absolute - I think the slickness this brings, both in how it glides but also in the finished result. When it was released, the product did have a tendency to clumpy in the bottle, but that has since been addressed. It can also congeal a little in the bucket initially, but again they have worked on that with later revisions.
ADS Hero - This is a hybrid polymer/surfactant product. It's probably not the strongest cleaners, but by the sounds of it, that isn't really your top priority. The reason why you would choose this one is the slickness during and afterwards. And with Si02 in the formula, it will help maintain a coating without the need for drying aids or toppers.
Opti-Coat No Rinse – This Si02 version of the polymer-type ONR doesn't get much love but its supremely accomplished. I personally think its slicker and glossier than Hero, while sharing its ease of use and dependability of the regular blue ONR. Smells nice too.
McKee's N-914 or DIY Detail Rinse-less - Not my favorites, but if you like the squeaky-clean feel, these would be worth looking at. Both are of the surfactant variety and have slightly "sticky" (for lack of a better word) to them. I also use these mixed at 128:1 as a windscreen washer fluid.
Considering you are familiar with ONR, I'd suggest getting a small bottle of McKee's N-914
and ADS Hero to see how they feel against your ONR benchmark.
