Are there any car detailing products that have proven UV protection?

I see there are a plethora of car trim products, both interior and exterior, that claim they have UV protection. However, I have not seen any independent tests to prove or disprove any of their claims or rank any products based upon their verified UV protection capabilities. Personally, I have used 303 for years. I think it's good product, but I am always looking for something that is proven to be better.

It seems like there would be someone, somewhere, who has done some form of honest testing for some of the major products, but I have yet to find such information. The closest test that I've seen is the YouTube video titled "Longest Lasting Trim Restorer Test. Meguiars "Ceramic", Chemical Guys, Cerakote, Ammo, & More..." by a guy who goes by the name "Repair Geek". He shows that 303 does seem to have a little, legitimate UV protection and that many other products might actually seem to accelerate damage to trim rather that protection against it!

Is anyone aware of any some honest UV auto product testing? Do you have a favorite auto rubber, plastic, etc., trim product that you use that you know has verified UV protection?

Finally, I work at a college. Do you think that one of my Departments might help me with a little informal testing? Who would I talk to, i.e., Chemistry?...Physics?, etc? Can you think of any methods we might try to compare some of the more common products?

Thank you!

Hey Ed,

I’d imagine any legitimate testing could yield cool results. With that said, companies may or may not provide a sample for you to use. Which may or may not be the same formulation as they sell to regular guys. The only way to eliminate this risk is to buy it yourself. Additionally, the reason there’s no verified testing is there’s no money in it. YT videos and empiric evidence round out anything f that could be legitimate.

Your best bet may be to cast a wide net at your college to see what they come back with in reply. HTH
 
This has done a tremendous job keeping the black stuff black on my 2015 Canyon. Outside 24/7. One caveat.... It's not compatible with certain rougher plastics. While it did a great job on the rubber trim and plastic parts of the side steps and bumpers On my truck, it turned a sill plate white on my Mustang.

None other than PPF. CarPro DLight claims to be the first but we shall see when Dmitry’s Garage measures it.
 
Optimum Car wax is the only ''patented UV'' product I've used. It smells great, and is fairly easy to use. One spray-two at the max per panel or you risk streaks. Leaves a nice Shine and offers decent hydrophobics. I copied a comment from Ron an admin on the OPT fourms:

Optimum Spray Wax has PATENTED UV PROTECTION - the government does not issue patents without extensive (and expensive) independent lab reviews. I did a study for Dr G and found that very few manufacturers even mention UV on their labels and no one has patented protection. -Ron@Optimum

If you watch youtube, you will see many, many detailing videos of waxes and ceramic coatings applied to taped off squares in hoods from junk cars. Generally the experimenter leaves the body panel exposed to the elements. The typical process is to wash the panel excessively and when the beading, or water sheeting is over, that product loses. You could do the same thing and see what paint oxidizes first by going dull or chalky or white. You could get a UV lamp to make the experiment go faster, because this process is going to take a while.
