How to Achieve Professional Quality Gelcoat Repairs

Gelcoat damage is an unfortunate reality that every boat owner faces sooner or later. It happens to the best vessels - whether you're running a Contender offshore or keeping your Yellowfin closer to home at Fort Myers Beach.

At Lopretto Marine, Southwest Florida's trusted marine repair center, we've tackled gelcoat repairs on practically every make and model out there. Drawing from years of hands-on experience, we've assembled this guide to help you understand the gelcoat repair process.

Understanding Common Gelcoat Issues

Let's start with the basics. Having worked on everything from SeaVees to Makos and Nor-Techs, we know what to look for. Our team has fixed just about every gelcoat problem you can think of.

Common Problems We Address:

Spider Cracks and Crazing

Thin, web-like cracks spreading across a boat's hull are a common sight, especially around stress points like cleats and deck hardware. These spider cracks can develop gradually from normal use or appear instantly after a hard impact.

Ignoring them is not your best bet, as even a hairline crack can quickly allow moisture to penetrate the hull. Once water seeps in, you’ll face escalating problems and costly repairs. In SWFL’s humid environment, early detection and intervention will help prevent minor issues from spiraling out of control.
Pinholes and Surface Pitting

Pinholes are small, round imperfections in the gel coat. Although they may seem minor, they indicate that something went wrong during the original gel coat application, such as trapped dust, air bubbles, or moisture.

Eliminating pinholes is not as simple as filling them and moving on. The key to successfully addressing these imperfections lies in proper surface preparation. Skipping this step will only lead to the pinholes reappearing in the future. Much like painting a house, achieving a smooth, flawless finish on your boat's gel coat requires thorough prep work.
Chalking and Oxidation

The Florida sun is no joke when it comes to your boat's finish. Even if you're super careful about maintenance, oxidation is bound to catch up with you eventually. You know the look - that chalky, faded appearance that steals your boat's shine. It's like a nasty sunburn for your gelcoat.

Luckily, oxidation doesn't have to be your boat's unavoidable fate. By waxing regularly and keeping your boat covered when it's parked at the dock, you can tack on extra years to your finish.
