Hi Bond Fillers

About Hi-Bond by Evercoat

Hi-Bond is the marine and fiberglass repair line from Evercoat, a brand with roots going back to 1953 and headquartered in Cincinnati, Ohio. Where Evercoat built its reputation on collision repair products for the automotive industry, the Hi-Bond line was developed specifically to address the unique demands of boat owners, marine professionals, and anyone working with fiberglass surfaces. The result is a focused, field-proven lineup of resins, gelcoats, repair kits, and specialty additives that have earned loyal followings in boatyards and garages alike.

Hi-Bond specializes in repair solutions for the most common fiberglass challenges on the water and in the shop. Whether you're dealing with stress cracks in a hull, a worn gelcoat finish, or structural damage that needs rebuilding from scratch, Hi-Bond's chemistry is engineered to deliver reliable, lasting bonds. The brand is recognized for manufacturing resins, thinners, thickening agents, and related products that give both DIYers and professional technicians the confidence to tackle demanding repair work.

Fiberglass & Aluminum Repair Kits

At the core of the Hi-Bond lineup are its Fiberglass and Aluminum Repair Kits. These kits are designed to simplify the repair process by bundling the right materials together — resin, hardener, and application tools — so users can address holes, cracks, and surface damage without guesswork. Hi-Bond's repair kits are formulated to cure to a hard, durable finish that bonds strongly to fiberglass, aluminum, and other common marine and automotive substrates, making them a go-to choice for boat hull repairs, body panels, and more.

Gelcoat & Wax Finishing Products

Protecting and restoring a boat's exterior finish is where Hi-Bond's Wax and Gelcoat products truly shine. The brand's signature Gel Coat with Wax is a premium finishing solution designed for use over fiberglass surfaces, formulated to cure to a tack-free finish that resists weathering and wear. Available with or without wax, Hi-Bond gelcoat products are used by marine professionals and weekend boaters alike to restore faded or damaged exterior surfaces to a smooth, glossy finish.

Resin Additives, Rollers & Spreaders

Great repairs start with the right supporting materials, and Hi-Bond's range of Resin Additives, Rollers, and Spreaders rounds out the product ecosystem. From thickening agents and coloring agents to polyester finish resins containing wax for a hard surface cure, these products allow technicians to fine-tune their laminating work for specific applications — whether building up structural layers with cloth and mat or applying a final finishing coat. Hi-Bond's general-purpose polyester finish resins are compatible with cloth, mat, and roving, giving users flexibility across a wide range of projects.
