Thanks for the tip..... I don't know about Peroxide on gel coat, but can't imagine it being any worse than other products or the road grime we drive through.........
I know when we had a rv park, we had a guy that cleaned big rigs. He used a piece of indoor/outdoor carpet with soap and water. I was shocked how well that worked. Very soft on paint
finished rv's. And I am talking that he used that method on million dollar rigs with out worry.
