What to you do to protect against the ultra rays?
We took our cue and used the advice of another couple who owned a Winnebago. He got up on the roof bi-monthly and sprayed and wiped down everything with 303 including the fiberglass roof itself. He also applied it to other surfaces on the coach like moldings and tires, etc. He used a NuFinish for the vertical surfaces quarterly although NuFinsh claims it protects for a year. They never had their coach under cover and after six years when they sold it last year, the buyer swore it was garaged because the roof and everything on it looked practically brand new.
We now try to do the same thing with the same two products. We buy 303 by the gallon at a spa-supply outlet and NuFinish at Costco. I know not all like NuFinish because it does contain silicone and Winnebago supposedly recommended that polishes with silicone not be used. But we called CDI, Winnebago's paint contractor, and they said it was okay and the notion the silicone is bad for paint has now been debunked by most experts. I'm not sure if that's been proven or not but if the initial paint contractor said it's okay, then we're okay with it too. NuFinish is widely available and is reasonable in cost.
Both products claim to protect against UV damage.
