Hi, I just purchased a used 2004 chaparral 310 with no bottom paint. I plan to use it in fresh water but will keep it in a marina slip. This is my first adventure with leaving a boat in the water I've heard of two (unconventional) ways of caring for the bottom of the boat. One is to use a product called mold release ( this is used in the fiberglass industry to aid in getting the fiberglass out of the mold). Has anyone ever tried this? The other one I read about is to use a coating of Lanolin. Anyone with any suggestions about these products I would like to hear from you. Thanks Tom
