What is "Fibron" roof material?

What is "Fibron" roof material for my 2016 Winnebago Minnie Winnie 22R? Fiberglass on Luan? To clean and wax the roof use established wax for Fiberglass siding?

winnebago usually uses Filon which is a type of fiberglass. Any type of car wax would be good to protect it.

I cleaned some light oxidation off mine with Meguiar's #50 then I maintain it with Meguiar's Flagship Premium RV & Marine Wax. They make other products for the initial cleaning but I had the #50 on hand and it worked great.

Your Winnebago has a Filon roof. It is a fiberglass reinforced plastic. It comes is rolls and they roll it in one long piece to cover your roof. Filon is also used on the sides of your RV.

The Filon is glued down to very thin Luan plywood. Like 1/8th inch thin. Which is glued down to large styrofoam blocks that make up your roof structure. Individually each item is weak but when properly glued together in a sandwich it’s a strong and light weight assembly.

Don’t mistake it for Gel Coat fiberglass, like a boat or other rigid fiberglass products. The Filon is thin flexible plastic with some glass fibers layered in. It is flexible but can tear easily if it is twisted.

Most recommend a yearly or twice a year waxing with a car wash/wax. I also use a spray on UV protectant called “303.”

Would LA's Totally Awesome spray be ok to use?

I have used Protectall spray cleaner/wax/UV protectant for the past 3 years, and it is the best product I have tried. Even after a proper washdown, the Protectall cleans the tough stuff that soap won't touch.
It lasts well, and is easier than 303, which I used to use.
Just spray, wipe with a cloth applicator, then final wipe with a clean microfiber towel (some modest elbow grease required) and it shines very well.

I use a stiff scrub brush on a long handle and a bucket full of a mixture of Kleen-flo Armashell Golden Wax Wash Powder. Rinse often with a hose that I keep up top. My wife sprays off the soap as it runs down the side because it's not good to let it dry.

This leaves the roof nice and clean with no residue that causes white streaks when out in the rain.

Here's me cleaning the roof.

A stiff brush, and do a small 4X4 foot section at a time.
