Hi David, I heard good things about dry ice and soda, Walnuts are supposed to be good too. (Mine was done the old fashion way with an abrasive wheel. The guy did a remarkable job, but you really have to know what you're doing to avoid digging into the gelcoat)
As for barrier coating I was advised against it as well (Supposed to trap moisture) and did not re-coat . I would go with the local knowledge / recommendations as different waters / climates dictate different approaches. I'm in fresh water witch is worse for osmosis. -Francois Rivard 1990 34+ "Take Five" Lake Lanier, GA > I am planning to strip all the old bottom paint off this fall and repaint > in the spring.
