Hi Ron,
I suggested N-914 because you were looking for a D114 substitute. Both D114 and N-914 leaves nothing behind and that's what makes them unique. But if you're looking for something that's left behind then you have lots of options.
I think it's great you are wanting to leaving something behind. I don't have a lot of experience with the McKee's 37 Rinse Free Wash and Wax but if I were using that (or any other rinseless product that has wax), I'd still use a spray LSP such as D156 or the McKee's FastWax afterwards. I think a dedicated spray LSP like D156 has more durable polymers than the waxes included in rinseless washes.
Have you considered using a waterless wash? This product is pretty much a quick detailer on steroids so it would fit the bill. This is my personal favorite -
Meguiars Rinse Free Express Wash & Wax D-115. This product IMO leaves some very good and durable protection. It leaves the paint shiny and slick. These LSP characteristics will always be there if you use this product once a week or every 2 weeks. Here's my review on this product:

And here's an article I wrote where I use D156 spray wax after cleaning the car with D114:

Hope this helps.
