Hi Bond Gel-Coat & Gel-Coat Repair Kits

Hi Bond Gel-Coat & Repair Kits: Professional-Grade Fiberglass Finishing

Hi Bond has built a long-standing reputation in the marine industry as a trusted source for boat repair materials, and that expertise is on full display in their line of gel-coat and gel-coat repair products. Whether you're a weekend boater fixing a dock scrape or a professional technician restoring a hull, Hi Bond's gel-coat offerings are engineered to deliver durable, professional results on fiberglass surfaces.

Waxed vs. Non-Waxed Gel-Coat Formulas

One of the standout features of Hi Bond's gel-coat line is the availability of both waxed and non-waxed formulations, giving applicators the flexibility to match the product to the task at hand. Waxed gel-coat cures to a hard, smooth, tack-free finish — ideal as a final topcoat that needs no additional bonding layer. The non-waxed formula, on the other hand, remains slightly tacky after hardening, which eliminates the need to sand between coats when building up multiple layers. This distinction makes Hi Bond's gel-coat line genuinely versatile for both single-coat touch-ups and multi-step refinishing projects.

Hi Bond White Gel-Coat with Wax is a premium-grade solution specifically designed for use over fiberglass surfaces. It contains Wax-Sol — a wax additive that promotes that clean, tack-free cure — and comes with MEK hardener included, so you have everything needed to begin a repair right out of the package. Sanding is recommended between coats where additional layers are applied, ensuring strong inter-coat adhesion and a smooth, professional surface.

Right-Sized Quantities for Any Job

Hi Bond gel-coat is available in multiple container sizes — from pints for small spot repairs to quarts and gallons for larger refinishing projects. This range means you're not forced to buy more material than you need for a minor repair, nor will you run short when tackling a more extensive job. Each size includes the necessary hardener, simplifying the shopping process and ensuring compatibility between components.

Why Hi Bond Gel-Coat Stands Out

Hi Bond has spent over two decades manufacturing marine repair resins, thinners, and finishing products — and that depth of experience translates directly into the performance and consistency of their gel-coat line. For boaters dealing with the inevitable scratches, dings, and weathering that come with time on the water, Hi Bond gel-coat offers a proven path to restoring the original gloss and protective barrier of a fiberglass hull.
