Removes even the most aggressive water spots with ease!
Water spots all over the gelcoat, windshield, and rails? Captain’s Fury Heavy-Duty Water Spot Remover is built for exactly that. Its heavy-duty formula breaks down even the most stubborn hard water spots on fiberglass, gelcoat, paint, and glass. Just apply, wipe, and rinse thoroughly. Your boat gets its clean, glossy finish back without hours of scrubbing.
Why Water Spots Are So Hard to Beat
Water spots aren’t dirt. They’re minerals. When salt spray, rain, or hose water dries on your boat, it leaves behind calcium, magnesium, and salt deposits that bond to the surface. Florida sun makes it worse by baking those minerals on fast. Regular boat soap can’t break that bond, so the spots stay put no matter how many times you wash.
Leave them long enough and they build up into a chalky haze that dulls your gelcoat, clouds your windshield, and takes the shine off your stainless.
Captain’s Fury Heavy-Duty Water Spot Remover goes after the minerals themselves. The formula loosens the deposits so you can wipe them away and rinse them clean. No heavy scrubbing, no harsh pads, and no guessing whether the spots are actually gone.
Use it on the hull, deck, and topsides, then move to the windshield, hardtop glass, and T-top frame. It’s also a solid choice for cars, trucks, RVs, and shower glass at home.
Captain’s Fury is our line of pro-level detailing products. We test every one on our own boats, and we only put our name on what we’d use ourselves. Made right here in the USA.

This is my second time purchasing from Captain's Preferred Products, and once again, I'm impressed! Their boat brush system is top-quality, extremely sturdy, and built to last. I also picked up their brush head organizer, which is a great addition for keeping everything neat, organized, and stored away.
If you're anything like me and love keeping your boat clean and looking its best, I highly recommend checking out their products. Definitely a great investment for any boat owner! Here's a video I did for my YouTube channel: https://www.youtube.com/watch?v=yWhq7nG5ogs

Excellent quality timely delivery
The kit worked great. I used it as soon as we took the boat out of the water and it removed the "film" caused by the salt water and prepped it for waxing.
Good price, quick receipt of goods & reasonable freight fee.
