The Captain's Take

I've been captaining boats for over two decades, and if there's one product I wouldn't leave the dock without, it's 3M 5200. This stuff is a lifesaver. I've used it for sealing leaky through-hulls to bedding deck hardware, and it never disappoints. It's the strongest, most reliable marine sealant I've ever found. For a permanent fix you can trust, 5200 is the only way to go.
