Discover Harbor Guard
Harbor Guard is a DIY-applicable marine coating that bonds to a boat's surface at the molecular level using Coval Technologies' CorLock technology. It's designed for gelcoat, paint, painted metal, and teak. Unlike ceramic coating, which sits on top of the surface, Harbor Guard forms billions of covalent bonds per square millimeter — producing a higher-gloss, more abrasion- and stain-resistant finish backed by a 2-year guarantee.

Harbor Guard and ceramic coating are both protective finishes for boats, but they bond differently and last differently. Ceramic coating sits on top of gelcoat, paint, or teak and typically needs reapplication every year. Harbor Guard bonds at the molecular level using CorLock technology, producing a deeper gloss, greater resistance to stains and abrasion, and a 2-year guarantee — while still being simple enough to apply yourself, without a professional detailer.
