Welcome to Harbor Guard

A better way to protect your boat than ceramic!

Made to actually last. A mirror-deep gloss with stain resistance that ceramic can't match — Easy to apply yourself, without the ceramic price tag.

Harbor Guard is a 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.

we are the Best

We don't cut corners, and we don't ask you to take our word for it. Every batch is tested. Every claim is backed up.

The CorLock Difference

CorLock bonds to your boat's surface at a molecular level — billions of connections per square millimeter — instead of just sitting on top like ceramic does. This is the real reason for the deeper gloss, the tougher protection, and why it doesn't wear off on you like everything else has.

Extensive Research and Testing

We don't just tell you it works — we test it first, with real ASTM lab testing for adhesion, abrasion, and impact. If it doesn't hold up under real conditions, it doesn't go out the door.

Complete Application Support

Detailed Technical Data Sheets and step-by-step instructional videos give you everything needed to prepare, apply and maintain Harbor Guard with confidence and safety.

What our clients Say

"As the General Manager of Safe Harbor Shelter Island, one of the busiest boatyards in the country, our shipyard equipment is always getting pounded by the elements and the rigors of near constant use. We applied Harbor Guard to our equipment the past year and not only has restored the luster to our boom crane, travel lifts and other equipment but it has sustained its luster and has made ongoing maintenance much easier. I have been amazed at the quality of the product, ease of application and durability in a demanding marine environment. "

Tripp Kerr
