Harbor Guard's CorLock polymer forms a covalent bond with the substrate — not a surface coating that peels or flakes, but a molecular bond that becomes part of the surface itself. The result is a hard, clear, flexible finish that displaces the elements rather than fighting them.
9H surface hardness. Half the application time of ceramic. No restrictions on cleaning methods. No wax over the top. No annual reapplication. For vessels in refit, Harbor Guard is an ideal final step — locking in the work and protecting the investment before the boat goes back in the water.
Restores and seals oxidized or faded gelcoat. Stops the cycle of polishing and protects the surface from UV and salt for years.
Applied over properly prepared painted surfaces. Maintains gloss and resists chalking, staining and UV breakdown.
Bonds to aluminum and steel. Prevents oxidation, salt staining and pitting on rails, towers, and structural metal.
Protects teak decking, cap rails and furniture while preserving the natural wood look and adding hydrophobic properties.
Fishing towers, outriggers, rigging and hardware. Keeps stainless bright and eliminates the constant polishing cycle.
Bait tanks, cockpit soles, vinyl and fiberglass interior surfaces. Cleanup after a hard day of fishing takes a fraction of the time.
Harbor Guard follows the surface profile topographically. It doesn't fill imperfections, but it seals them permanently from the elements and restores gloss to oxidized and faded surfaces. What a crew polishes over hours is resolved by one coat and a few hours of dry time.
For boats coming out of a refit, Harbor Guard is an ideal finishing step — protecting new work and ensuring the vessel holds its condition long after it goes back in the water. We apply it at our San Diego location or can come to your vessel at the dock.

Sam Weisman — 64’ Yacht Fisher"As a boat owner who's battled Cabo's sun and salt, I know the constant upkeep. Harbor Guard changed everything — bonding to the surface and ending the need for endless polishing. Nothing else compares."
Kirk Jackson — Owner, 75’ Northstar"We applied Harbor Guard to our boom crane, travel lifts and equipment. Not only has it restored the luster — it has sustained it and made ongoing maintenance dramatically easier in a demanding marine environment."
Tripp Kerr — GM, Safe Harbor Shelter IslandNo. The surface must be properly prepared and completely free of wax, silicates, grease, and oil for the covalent bond to form. We handle all surface prep as part of the application process.
None. Unlike ceramic, Harbor Guard isn't sensitive to soap pH, hot-sun washing, or harsh cleaning products. You can clean it with acetone and it won't affect the finish.
In most cases, one. Harbor Guard is thin and bonds deeply. On heavily oxidized paint, a second coat may be needed for uniform finish. We'll assess the surface before starting.
If applied to a properly prepped surface, no. Harbor Guard forms a covalent bond — it's not sitting on top of the substrate, it's part of it. Peeling only occurs when surface prep was inadequate.
Product ranges from $200 per liter to $799 for a four-liter case pack. Total cost depends on vessel size and the surfaces being treated. Contact us for an estimate specific to your boat.
