I have a 2016 Jayco fifth wheel that is in use most of the time and therefore constantly exposed to the sun. Was wondering if anyone could suggest a product that they have had good luck with for reducing the impact UV rays on the sides and roof?
I would recommend a polymer base automotive polish to use on the sides. Polymers tend to resist UV rays better than a carnuba based polish. Pure carnuba will begin to break down in 5-7 days in the Sun. The polymer based polishes I am familiar with are advertised to remain protective on the surface for 1 year. Also a wax based polish will ALWAYS cause water to bead on the surface. These beads are potential water spots. Polymer based tends to sheet water off thereby reducing the incidence of water spotting. Hope this helps, Dave
