I have also used the sand man with great results. Took off alll the old paints with no damage to the barrier coat at all. Jos just curious...our bottom paint lasts two years and we are in similar areas. Do you do any maitainence on it during the year such as use a diver or dive and maintain it yourself. Can you touch up you chipped area and get another year out of your paint instead of just adding a few new layers to it?
Hi Chef, we had a diver under the boat about mid-way through the year, and when we hauled the boat, the bottom was actually pretty clean. I probably should have made the yard just wash lightly, because there wasn't much need to hit it hard.
I would think that if we sanded and touched up the keel and strut (which would mean another coat on them probably), and then just sanded and touched up where the chips are on the hull (not many), then we'd be good to go. The paint appeared to be in good shape before the wash.
I'm just surprised the power wash took off so many chips. Pounding into the chop on the Chesapeake didn't cause it, so it's not like the paint was just "loose".
It would be nice to get another season out of it, then I can sand off more or even soda blast it next year when it'll need more fresh paint anyway.
Just out of curiousity, since the chips are more on the keel and the strut, could the paint flaking there be a galvanic thing? Or am I thinking too hard?
