I was wondering if its good practice to remove the diving board for winter? If so, do you also remove the base each time? I currently have mine removed as its new to me and wanted to check for any damage on the underside of the board and inside the base. I coated the bolts with a heavy amount of water proof grease since they are totally exposed but would this be a good idea to do every winter or should I leave the base attached? Will the base fill with water and cause the bolts to rust even more if not removed?
