Hi Bob, For what it's worth.......... Many years ago when I repainted my 29 foot sailboat hull, using LP paint, I wound up with some sags, and brush marks. (it was tough trying to keep a wet edge moving...) My "helper" doing the painting, offered the following advice. He said back off about 10 feet from your work and take another look. What do you see? A nice shiny new looking hull. Once you are in the water, nobody will see the slight color mismatch or brush strokes. He was absolutely correct, though the sags bothered me each spring when I was getting ready to launch again. But, as the years went by, I was happy that the hull looked as good as new, and the next time I painted a hull, I was a bit more knowledgeable. I also lost any qualms about opening and filling craze cracks; or repainting a hull. Enjoy your work. Connie
