I am a user of Island Girl products, and am impressed with their performance. However, the gel coat on my boat is affected by atmospheric particulates in a way that other boats aren't. That is, there are numerous black streaks and discolorations on my gel coat that are not present on other boats. I believe that rain containing smoke particulates is causing this problem. Using Island Girl products, what is the best way to deal with this problem. Is there any way to prevent this from happening? Thank you. Don Barber
