FAQs
Harbor Guard can be purchased through distributors or direct where other channels are not available.
Yes. Harbor Guard is easy to apply. Please read the Technical Data Sheet carefully and follow the instructions. Then watch the Learning Videos in the tab above.
No. Harbor Guard will not stick to ceramic coatings, wax, oily surfaces or surfaces covered in grease. Our Technical Data Sheet can be downloaded from the website to review the proper surface preparation before applying Harbor Guard.
Ceramic coatings are very sensitive to soap pH, washing in the hot sun, and soaps that contain wax or other harsh chemicals. The use of these products can quickly destroy an expensive ceramic coating. Harbor Guard tolerates virtually any cleaning method. You can even clean it with acetone, and it won't affect the finish.
Harbor Guard is a two-coat system. We recommend applying two coats during the initial application for optimum coverage and protection. Typical coverage is 23–28 m²/L for the first coat and 30–35 m²/L for the second coat. Wait 24 hours before applying the second coat, and always follow the relevant Technical Data Sheet.
Harbor Guard is topographic, meaning it adheres to the profile of the substrate and leaves a gloss finish. On older paint and gelcoat, Harbor Guard can highlight surface imperfections, although they will now be sealed off from the elements. Harbor Guard preserves whatever state of finish is achieved after proper preparation of the surface.
No. Harbor Guard is the last coat over a properly prepared substrate.
No. Due to the nature of Harbor Guard's bonding mechanism, it will not peel or flake if it is applied properly.
Harbor Guard is not designed to be removed. When properly applied, Harbor Guard protects and seals off the substrate from the elements, producing a long-lasting, smooth, clear finish for five-plus years. Chemicals cannot remove the coating. If you make a mistake, you can remove it with acetone while it is still wet.
Harbor Guard is a single-component, moisture-cured polymer that can be applied to a wide range of marine substrates. It's easy to apply, long-lasting, displaces harmful chemicals and is significantly more cost-effective than ceramic coatings and other related sealants.
CorLock is Coval Technologies' proprietary technology that forms a unique, covalently bonding protective coating. The result is exceptional strength, hardness and flexibility, with a thin, abrasion-resistant, chemical-resistant, UV-stable, high-gloss finish.

Yes — extensively, in the real world. We've been testing it on actual boats since 2020, when the division was first formed, not just in a lab. Sun, salt, fuel, everyday wear — the whole list of things that actually wreck a boat's finish. If it didn't hold up out there, we didn't sell it.
