My BJ28 has been in a marina for the past five months. We pulled the boat onto the trailer in preparation for hurricane Irma. Fortunately for us, the storm looks to have moved west far enough to spare us. While the boat is out of the water, I want to clean the bottom. I used Petit Hydrocoat bottom paint. No barnacles, except on the stainless steel keel protector, but there is quite a bit of green "scum', especially from the waterline to the chine. I removed the green scum on the sides with a stiff brush and lots of water, but must also be removing a layer of bottom paint, judging by the color of the rinse water. The bottom is pretty clear, just sort of stained green. I can clean it, but am I doing more damage than good? After I get all the barnacles off the keel protector, can I use bottom paint to keep it clear?
