I have wondered if it would work, it does. I was touching up the paint on my boat and thought I'd try it. I did not pull it over enough to get all the way across the unpainted portion of the area under the bunk but I can paint what I can and the careen it over to the other side and get the rest. So the only portion you can not get to is the trailing edge of the centerboard and in the trunk. I'll get them next time put it on the lift.
