I mean, logically think about it for a second...if car manufacturers wanted their paints to last on their cars, they would create stronger paint and clearcoat processes that can last for years and years without much maintenance. it's no different than the wheel and tire aftermarket. paint shops an detailers wouldn't have a viable niche to fill if paints lasted a long time. same with wheel shops, if dealers offered the wheel you wanted, their would be no need for the aftermarket. same with all the car polishes, wax, and wash products. car manufacturers spend most of their money on design and vehicle technology and less focus on paint technology. most factory paint jobs are just stage one with maybe one layer of clearcoat. adding a few more layers of clearcoat alone would not hurt their bottomline one bit or add much more weight to the car....(i.e Bentley's are sometimes up to 14 coats of clearcoat) but that doesn't matter because they know the aftermarket for detail products, paint shops, etc..will always be there.
concerning cars being on lots for years was hypothetical, but I've seen them be out there at least 9months. it's not abnormal for dealers to keep cars on the lot. yes, they move them around, but they still end up being outside on another lot catching heat from the sun. and I can tell you from experience that when we got cars in, we weren't instructed to polish or wax em' most times. most times, all we did was powerwash it, vac it, and dry it off.

First thanks for your attempt at a response, I say that not to be mean as you did reply but you did not attempt to answer the questions I put forth and after 15 years, as you claim, being a "pro detailer" these are basic things you should know.
The benzotriazole UV blockers used in clear coat paint have a half life of 5 years so after about 10 years their should be around 25% of the UV blockers left. These UV blockers reside in the uppermost layer of the clear coat and as long as one cares for their paint properly their clear coat should last the life of their car.
Now many things can contribute to either an early paint death or an increased paint life, such as how is the car driven, where's it parked and how it is cleaned?
Even how the paint was applied at the factory plays a role. The instruments which regulate UV blockers to paint ratio may be off a slight bit and your car may not have gotten the proper amount. Clear coat is not a natural inhibitor of UV nor does wax or polymers have a natural UV blocking system, it MUST be added to both paint and products which claim they block UV, even though most of those are using a sunscreen much like that used in skin protectants.
Now I have been detailing for 18 years and I have one client with a 15 year old NSX. The paint , even though it has its share of scraps and bumps, is still solid and shows no signs of fading. It helps that the paint is silver and it's always garaged during the hot times of the day and also that it's properly cared for since day one of it being bought. It has over 250k miles so it's not a garage queen.
My point is that never once was it washed with any dish soap and after being washed, cleaned and polished everyone seeing it thinks it's new and can't believe it's 15 years old with that amount of mileage.
So again your personal "paint philosophy" is incorrect and not based on what's real. I am in no way correct about all things detailing but if I'm uncertain about something I go to those who know, paint chemists and product manufacturers, and ask them questions concerning these things. Have you?
So before you state that my replies are "arrogant" and "nonsense" or that I'm a "moron" I suggest you look into your claims and see if there is any science to back it up and then go back and read my statements and point out to me where I am spewing "nonsense".
Also, where do you get your information about OEM paint application? You have a misunderstanding about it so I am guessing that your source is incorrect. In other words you're passing on misinformation about OEM paint applications and how it's done. Wouldn't you want to have a correct understanding of it so you can pass that knowledge on to others and your clients?
Lastly, does the Federal Clean Water Act allow the dumping of dish soap (or any heavy cleaning detergent) down the sewers?
