I have a new Ranger bassboat that I want to keep at my dock, in the water, on Lake Marion in SC. Problem is, the hull and anything in contact with the water becomes fouled within a week or two. I have had difficulty removing the crud. Question: What product(s) and method(s) is/are best for removing crud while not bleaching or harming the gel coat? BTW, the hull color is a crimson Red. I realize that after crud removal, one must put on a new coat of wax.
