I say, shrug. It's OK. Its biggest drawback is the amount of dust raised by removing the residue. You have to use thin, thin coats.
If you prepare your surface properly, you will get a nice shine from NuFinish. Not killer, but decent enough. Think, Zymol blue cleaner wax but lasting a lot longer. It's a cleaner polymer, in that sense. It's got a lot of shine, but less depth than a carnuba.
I have had it last 6 months. Longevity of protection is its strong suit, IMO, and is why I've used it in November, here in NE PA (the heart of the salt belt). That's the reason I used it on my dad's Trailblazer; he's 76 and doesn't wax at all except when I take his truck from him and do it, about once a year.
As for trim staining, you do have to be careful. I follow with B2B. But it was a witch to get off some places.
I've only been Autopian a short while, but I have firmly bought into the idea that it's a process, not a product. If you clay, then remove swirls, then glaze, you can finish up with NuFinish and be proud of your work.
Sure, you can also finish up with Souveran, or S100, or AIO and SG, or#26, or Zymol blue or Turtle Wax. I will go out on a limb and say, if you did all the other steps right the car will look great no matter.
