Boat bimini tops and t-tops protect you from the sun and surprise rain showers while you're on the water. But they need protection, too, from UV rays, salt spray, bird droppings, and environmental contaminants. Over time, marine tops can lose water repellency and color. Our bimini top care and t-top care products clean and preserve marine tops to maintain their functionality and value. 303 and RaggTopp make excellent products for both vinyl and fabric bimini tops and t-tops. With regular care, boat tops will look like new season after season.
