Nearly every product claims UV protection these days. No one quantifies the amount of UV protection their products / coatings actually provide. Research has shown that even ceramic coating provide very little UV protection. Most coatings / waxes and sealants provide environmental protection to reduce the deterioration of the top layer of clearcoat.
I'm sorry but i do not have the links to some of the research papers that I got this information from, but this is not just my opinion.
