Rejex works great. Had my hull done this past spring after a little clean up with 3M Finnesse II. Boat washes up nicely and accumulated much less "ICW Mustache" from Baltimore to Massachussetts to South Florida, than it did last year, and what did accumulate came off easily. We spent the summer on a mooring and the boat got used a lot, but seldom had a chance to wash it down. Glad I made the investment.
