Our antifouling test panel went in the water June 2, 2010. I pulled it today(June 5) primarily to check on the portion coated with Easy-On Bottom Wax. Easy-On is said to be rated for two to three days of fouling protection in salt water and a week in fresh water. So far, so good: After three days in this brackish tidal creek, there was no growth evident. If growth does appear, it's supposed to be a snap to just scrub it off. Time will tell. But for now, it looks like a fresh coat of Easy-On will let trailer boaters wet-store for a long weekend without worry of growth.
