In November 2015 I had the boat painted in S Fl. Also, had the running gear cleaned and painted with Pettit Prop Coat Barnacle Barrier. It held up surprising well I think better than propspeed and less money. The guy that painted the running gear used some type of strong cleaner to remove barnacles, etc Anyone know what that product may have been. It was not muriatic acid more like a gel. Its that time again.
