Time to consider bottom paint and I read that some say leave it bare for freshwater. Can I just sand down the old paint and go back to good old fashion wax job. Also would stripping hurt the gel coat? as opposed to sanding? We will be trailering our 25'O'DAY and I keep reading that it not worth the time and expence, but I still would like a nice looking bottom, nothing looks worse than half an old paint job. MLM
