I cut a access panel in the floor of my 19' bayliner capri to store oars and water skis. It was painted with a white oil based paint. Unfortunately, water that sits in there from rain, wave action, etc. is creating mold on my equipment. I am considering sanding and repainting with Interlux brightsides and prekote. Do you think this will help or should I create some sort of shelf for my gear?
