Hey <br /><br />Why do I get a black film all over the boat after it rains -- I dont mean just the black streaks but actually like a thin black film which does not scrub off with soap. I have to use Simple green, but I dont want to scub with simple green every time it rains. Can this be some kind of reaction from the wax????? It is very frustrating when the boat is clean but then after it rains it looks filthy. Any Ideas/how can I stop this from happening??? Thanks COOL IT!!!
