I got the ceramic coat from the dealer when I bought my Triton as it was red, and I did not know this at the time but if you see any red tritons that are a few years old getting around they are all pink, unless someone has given it a cut and polish.
The spiel from the salesman was that the paint protection had a guaranteed 12-year protection from fading. I was very dubious of these claims, but as I had it in writing, and I knew red cars are more prone to fading, I paid the extra for the coating.
Well blow me down, less than 12 months later I had a pink Triton! Took it back to the dealer and they got the paint protection guy in, and he blamed the paint. What it was is, that Tritons simply don't have a clear coat, so like all cars used to do, they fade. The paint protection does stuff all and they wouldn't back it up. Fortunately, the car dealership was great and stuck to their word that they would fix it one way or the other. Ended up getting a full respray (with a clear coat this time) at a cost to the dealer of $9K and it stayed shiny and red for the next 10 years I owned it.
I don't think that ceramic coating/paint protection is worth what you pay for it. You may as well just wax it yourself once a year, as even though they claim it lasts for years, it doesn't.
