I am looking for MAXIMUM protection from the sun for certain applications. Mainly, for cars that live outside (no garage, carport, or cover) what types of products are best to keep the clear coat protected from the sun? I know there are benefits from coatings, especially that they last longer once applied but setting that aside what types of product(s) will offer better protection from the sun??

Just to give an example I have been using Klasse AIO + Klasse Sealant (+ wax sometimes on top) but I am wondering how does this package protect from sun VS say Cquartz, Opticoat, etc??

Also, when using the Klasse AIO and Sealant which of the two offers better protection from the sun the AIO or the Sealant???

Is there some other type of product that offers the best UV protection???

Thanks!!!
