Inspecting a Gel-Coat Fiberglass RV Roof

I had a viewer recommend how to inspect roofs. There are many different RV roofs so I figured I would start a series and record and inspection whenever I'm on a roof. This is a Newmar Mountain Aire with a true fiberglass one piece roof. I'd recommend dicor lap sealant on the roof, 100% clear silicone on the sidewall and radius, and cleaning with soap and water with a wash and wax. Thanks for wathcing.
