Can You Use Ceramic Spray on a Boat?
Wondering if your ceramic spray is safe for your boat? Most aren’t—but Tough As Shell is. Here’s how to use it properly on gel-coated and marine surfaces.
Not All Ceramic Sprays Are Marine-Grade
Many popular ceramic sprays are made for automotive clear coats—not boats. That’s why they don’t bond well to gel-coated surfaces, wash off quickly, or leave streaks on fiberglass.
Why Tough As Shell Works on Boats
Tough As Shell is designed to work on more than just paint. It bonds effectively to:
- Gel-coated fiberglass
- Polished metal trim
- Glass and clear plastics
- Marine vinyl and non-porous surfaces
That makes it an ideal protectant for boats, jet skis, and other watercraft that are exposed to harsh UV rays, salt, and hard water.
What It Protects Against
- Oxidation and sun fade
- Salt buildup and mineral stains
- Water spots
- Surface grime and organic buildup
How to Apply Tough As Shell on Your Boat
- Clean and dry the surface (foam cannon or bucket wash)
- Lightly clay if needed for surface decontamination
- Mist Tough As Shell onto a section (3x3 ft)
- Level with a microfiber towel
- Buff off streaks with a second clean towel
Use it on the hull, deck, vinyl trim, stainless, gel coat—you name it.
Pro Tip:
Unlike some marine protectants that leave a greasy film, Tough As Shell flashes clean, doesn’t attract dust, and lasts far longer than waxes or detail sprays.
