Well this is our first year of sailing and the Hunter 19 is on the trailer for the winter We just had it bottom painted last spring and some of the paint is scuffed off and the rest has some green algae on it.Any suggestions on what to do now Should I powerwash the paint or just leave the algae sit? It seems just with brushing the paint that it comes off Should I put another coat on in the spring before launching her again? Thanks
