SSQ- The regulars here might consider this another one of my "Autopian Heresies"

but anyhow...
It's perfectly reasonable to not want to spend too much time on detailing. "One-step" products can work *very* well; I know people who use them and while their cars might not be what some Autopians consider "perfectly detailed", they still have great looking rides.
Often just using a cleaner wax from time to time and then topping with a "straight" wax now and then can work great. I've known people who never did anything more than this combo and their paint held up (and looked) fine for many, many years.
The #26 is a "straight wax" and so you should probably do some kind of prep before using it, at least now and then. Clay, a cleaner wax, or a mild polish will all do something to prep the finish for the #26. Which of the three you use depends on the paint's condition. But *do* perform some kind of prep at least once or twice a year.
Next time you wash the car, look it over closely and see what it might need, prep-wise.
I *would* clay it now and then. It really is worth the effort. Clay will pull out contaminants and make for smooth paint. If all looks well after claying you could just apply the #26.
If there are no swirls you could also go over the freshly-clayed car with a cleaner wax. It would remove any residue left over from the claying and will provide a few weeks worth of protection. Then apply the #26 after the next wash. This is probably what I'd *really* advise you to do. Just keep the cleaner wax off any black trim.
If you *do* have swirls/marring (and they bother you), I'd use an easy-to-use polish that also provides some protection (such as 1Z Paint Polish). The 1Z PP will protect the paint for a few weeks all on its own. As with the cleaner wax, you could simply apply the #26 after the next wash.
Then apply the #26 from time to time whenever the beading starts to look like it's dropping off.
You *can* have a nice looking car without spending a lot of time on it
