I have an 1989 bowrider with chalkey bottom paint and it makes a mess when washing. I it use only in fresh water lake and trailer it, but may leave it in. A local marina told not to repaint, that the bottom paint polutes the water as it wears away. The bottom is a mess and it is easier and cheaper to have it painted. They recommend removing the paint with EZ-OFF, but the boat is on a trailer with bunkers not rollers. How would I get it off the trailer. <br />
