Best UV barrier on the market?

So to be clear, some of you are saying that Aerospace 303, doesn`t really stand up to being outdoors? Mainly, it gets washed off by rain?

I wouldn`t use it for exterior protection if looking for durability. Didn`t last long on the hot tub cover. Doesn`t last long on tires either.

Which offers the best UV protection?

The one that can prove it. So far, no company has shown any, yet people eat up this UV protection garbage. #fakenews

Eh, pick something that oxidizes readily, e.g. there are a few seals on the Audis that do it *fast* under sunlight, and see if anything beats whatever you`re using now. E.g., on those Audi bits, they hold up better if I use OCW on them than they did with FastFinish (which displeases me as I prefer some things about the FastFinish).
