It also has anti-bacterial and anti-fungal additives to make it mildew resistant. Marine vinyl is great for outdoor applications or anywhere else it would be exposed to direct sunlight or moisture. Marine grade does not necessarily mean that it's higher quality than standard vinyl, just that it's UV and mildew resistant. Check out the video for more info!
