I have a Sea Ray that is always rack stored and never left in the water over night. Most of my boating is to the usual spots----Poormans, Gull, the Moot, etc. It seems that after a few times of use the bottom starts to develope a green tint. I use Slimey Grimey to take it off, but I was wondering if anyone else has the same problem and if there is a solution to prevent this. Bottom Painting is out of the question. Thanks!
