Video was interesting. The guy tries real hard but misses the point. A UV protector is a UV absorber such as chemicals like benzotriazoles or benzophenones. Carbon black is the best UV absorber which is why most weatherable plastics for outdoors are black. UV absorbers work in that they absorb the UV energy before the polymer does so the polymer doesn't begin to degrade. Two issues with UV absorbers. First they are consumed. They absorb the UV energy by rearranging their molecule and converting energy to heat. Second, and this is the issue with the wax, UV absorbers require a certain path length of light before they can react to absorb the UV. The thickness needs to be at least 4 mils to give the UV absorber time to react. A UV clearcoat needs to be at least that thick or it will be ineffective. So these waxes won't offer simple UV absorption protection because they are too thin. They will however protect the surface due to the wax residing on the surface and avoiding surface erosion of the polymer. The proper term would be weatherability protection and not UV protection. Class dismissed.
