Yes, it is that good. No, it's not a miracle.
It is easily the longest-lasting, most chemical-resistant paint protection product short of a ceramic coating. Will it last a full year? Not for a daily driver parked outside 24/7 in the Pacific Northwest. But it will last well for 7-8 months under those conditions, enough for the rainy season. Nothing else will short of a coating—not Collinite 476, not Sonax PNS, not any of the "ceramic" spray coatings (except maybe Griots 3-in-1). So it will last 1/2–2/3 as long as a coating-lite such as Gyeon Can Coat or Carpro Lite, but it is several times cheaper per application (a tin is 2/3 the price and is good for 15-20 applications) and it does not require being protected from water for 12-24 hours like the coatings. (Do not apply any coating unless you can keep the vehicle inside for 12-24 hours. I don't have a garage, so I can't use a coating. Plus, it is much less prone to water spotting than coatings. It takes a bit longer to a)pply than the coating-lites, but not much, and there is no cure time. It is not difficult as long as  you apply it very thinly. Do wear gloves and a mask, and store it in an air-tight container or outside your living area.
