I have 3 different clear coats in my paint locker, from different manufacturers none say any thing about UV protection.

Here is one manufacturer of aircraft paint that has clearcoats that mention UV protection. Endura Paints
Then there is also the Sherwin Williams AcryGlo paint system for general aviation that comes in solid or base coat/clear coat metallics that offer UV protection. AcryGlo paint system



WE paint aircraft almost every month or two. most applications are URA products and have no requirements for a clear coat.

Clear coat is used when you do not want to feel the line on a different color stripe. It provides a smoother surface that some people, including me, want. The same goes for my RV. I have painted stripes on my RV and the clear coat levels out the paint surface so that when you rub your hand over it, it feels smooth. Both of my planes had stripes and I wanted a smooth final finish when I painted them.
The Sherwin Williams SKYscapes paint system is also a base-coat clear coat system for aircraft.

Obviously a base-coat clear coat paint on an aircraft or an RV will cost more and take more time but in my opinion it provides a better final finish and better protection from the elements.
