ZEP wet look...need UV protection?

Thanks for the replies...yes, it does seem that most, not all, that actually used it like the results and those that never used it say its no good. My old 89 class C had fiberglass strands poking out it was so rough. Washed it, used barkeepers friend and scouring pad, even had to use fine sandpaper to get it smooth. 6 coats of zep and it shines like new almost. I was just wondering if a UV protector is needed.
