Hi everyone! Had to park at a different location for a month and didnt realize the underground sprinkler was spraying my fiberglass siding on my 23 RBM and now one side is covered in hard water spots. What is your best recommendations for removing those spots? I did a search and didnt see anything. Thanks in advance.
When I owned boats this was the only product I would use. There are others out there not but Ducky was the best in my books. I will tell you that lakes in our part of the country have the hardest water going.
