wannafbody, my reply to your pm was too long, so I'm posting it here.
NXT lasts a long time, but I don't think even Meguair's would claim a year for it.
I'm not sure what the haze you're referring to is. And for residue around the emblems, well if you took a bottle of NXT and left it open, it wouldn't evaporate to nothing, it would dry up and leave a chalky residue. But that's not a film, and this is all about film technology.
We're talking about films of chemicals a few molecules thick. If you were to apply the product and then pull the car into the garage and leave it, then it would probably last a year. But as soon as you pull it out into the world and the film starts to get attacked by dirt, pollen, pollution, rain, snow, salt, gasoline, etc then the film starts to abrade. When you get swirls from washing, those swirls cut through the film and create huge gaps. The molecules don't automatically reconnect over that gap, the film doesn't "heal"; instead, everywhere there is an edge, the film starts to wear away.
There are no standards for what constitutes "lasts a year" or "lasts five years". No one comes around and checks. If you read the fine print that backs these claims, they don't say that their product lasts five years. What they do is they warrant that if you apply their product to a new car they will warrant the finish for five years. They don't say that it will last five years; they guarantee five years of satisfaction. That's a very different thing. I have 16 years selling aftermarket products to end users (individual consumers). I know what these chemicals are, and I've read the fine print.
The best paint sealants I know of will last about 6 months, outside 24/7. That's pretty good, I think; that's a tough chemical. It's a generic bulk product sold directly to volume users. It is a standard aminofunctional silicone polymer that uses ptfe as a carrying agent to increase spreadability. The best of the systems sold to consumers include a paint cleaning step to help increase durability; if you apply the sealant over contaminants, then the film will be compromised sooner due to the contaminants. You might also notice that the one-step products like NuFinish have a high cleaner content, for the same reason. It's not about bonding, this stuff sticks to anything once it forms a film; it's about increasing durability by removing contaminants that compromise the film.
Remove yourself from product claims for a moment and ask yourself: if you were a small manufacturer that developed a chemical with these properties, the ability to maintain a film against the elements for five years (or even one year), what would it be worth really? Is it credible to think that such a company would succeed where DuPont, Monsanto, 3M, GmBH, BASF and others couldn't? (I leave Meguiar's out because large as they are in the car care field, they are like a fly to an elephant when it comes to these guys.) Engineering is really all about research money. What is more credible is that these chemicals have been around a long time and are being used by many different companies for the same thing, and that they are being MARKETED in different ways by some companies.
If you want to get comparable product for cheap, order some of the bulk sealant from Chemical Guys or any one of a number of places. If you get a paint cleaner and a sealant you will have both parts of a two part system... starting to sound familiar? If you get cleaner, polish, shampoo, and sealant, you have Finish Kare System.
There's nothing new here, other than implied claims. Look at the websites pushing 5 Star: "trustmymechanic.com", "cardetective.com", "buy-and-sell-car-secrets.com", etc. Part of the marketing ploy is to surround the pitch with other "useful" content, making the recommendation of 5 Star look off-hand and like it's coming from a consumer advocate. Read the 5 Star website closely; all you'll see is testimonials. Read the "independent test"; 5 Star isn't compared to other products, it is compared to... nothing, and it is compared for its ability to repel distilled water. Any other paint sealant might have worked as well, or better, or worse. But we can't tell that from the test. All we know is that "a major car wax" failed after 25 washings. Kit? Turtle Wax? Meguiar's Gold Class? Who knows, we are never told.
If it was that easy, everyone would do it. But it's not.
