I get yellowing or hard water stains on my fiberglass boat after just one trip on the water. Has to be hard water because the only thing that takes it off is a lime away product. Has this happened to anyone else and what do i do to stop it. I have waxed the sides and hull afterwords but it returns and I have did nothing at all after removing it for it to come rite back. Any super products out there or a company that knows of this situation.
thanks
