We have a friend that is a traveling detailer. I ask some of the same questions back a couple months. He indicated the best have to be used indoors, but there is a new one that he said will be able to install out doors in Sun lights.
He's done a number of late model Lance travel trailers and the front skins are tought to keep a shine on. He would give a recommend product!
A number of Youtuber RVers like 'ZEP' floor wax. Couple coats in a short amounts of times. <https://youtu.be/PueUu9BTP68>
Good luck
