exterior coating
In Phoenix AZ there is a company who advertises an exterior coating for RV'S,Trailers etc. (fiberglass) that never has to be waxed again. They say they completely remove all stains from the fiberglass...

If your rv is in good shape, just keep it waxed on an annual basis. The once a year for $250 is about what a good wax job should cost if you have someone do it.
