RV Wax vs Polymer Sealant: Which Is Better?

Both protect, but they last different amounts of time.
Is wax or sealant better for an RV?
Wax gives warm gloss and protection for a season. A polymer sealant lasts longer and resists UV and grime better, making it a good choice for RVs that sit outdoors. At Slums, Wash & Wax is $17/ft and the Polymer Paint Sealant add-on is $10/ft with that package.
