I've been mulling this over. I'm entering my second season as a boat owner, and last year I put on a coat of Hyrdocoat during my initial haul out, even though there seemed to be quite a bit of old buildup (the prior owner also used Hydrocoat.) This year, as last year, when I had it hauled and pressure washed, there were maybe a dozen or so areas that chipped away down to the barrier coat. These range in size from quarter to saucer-sized. I'm seriously contemplating just touching up these areas and the water line, instead of adding yet another coat.

One thing I will say is that I had no visible growth on the hull after several months in the water (upper Chesapeake.) So the paint seems to be doing its job in that respect. I just think there's way too much of it on the hull.

Sorry if this constitutes a thread-jack!
