Man, I couldn't agree more. And for 99% of the folks out there, those results alone are going to be enough. The question is, do you want to spend hours trying to achieve that 1% more out of your shine or do you want to DRIVE your car? I have yet to have anyone walk up to me and say, "Man, that's some great looking wax!"
I bought mine to drive and although it's clean, I drive the hell out of it. With 150,000 on the odometer, people who don't know still ask me if it's new. It's 13 years old!
you may be a bit backwards in your thinking here, because it's true that wax can change the look of paint. different waxes can have different effects, take colored waxes for example. that layer is only a few nanometers thick, but it makes a different, just like it makes a difference for protection.
but in terms of people wanting a wax for getting past that 1% difference. i would assume that the average consumer wants a wax that will help their not so perfect paint, look better. all of us have even observed how some waxes, or glazes, or sealants will cover up scratches to make a much smoother and reflective surface.
when it comes to the OCD of paint polishing, and getting it 100% perfect. the paint itself will be as close to completely flat, and level, and glossy as can be, and a coating or wax on top of it won't make a difference in the appearance in terms of gloss, or reflectiveness at that point, but it can have an overall effect on the appearance, as we have seen the darkening characteristics of wax through the pictures of tapelines on polished vs waxed surfaces.
if you want to go back to your makeup analogy. you won't be able to tell what kind of makeup she used, and you won't be able to tell what kind of wax was used, just like in your video too, you won't know when it is or isn't used on a perfect surface (which most people don't have). and you won't be able to tell if a woman has even used makeup if her face is already in pristine/perfect condition.... but change that perfect skin or perfect paint to rough/dry skin with imperfections, and paint that is swirled up some with cobwebs and dull ness. and then that is when you can start to really see the helpful effects of makeup/wax.
(btw, just last week a guy walked up to me at a gas station and asked me what kind of polish and wax i used because my car looked great, ironically the paint isn't anywhere near perfect, but it has more than a few layers of protection on it, so it still shines brightly)
