Protection guide

Salt water is eating your gelcoat. Here's how to stop it.

Updated July 2026 · John's Pass Boat Care crew

Gelcoat looks like armor, but it's porous. Salt spray dries into microscopic crystals that sit in those pores holding moisture against the surface, while Florida UV — among the strongest in the country — breaks down the resin around them. The result is the chalky, faded look every boater here knows: oxidation. Left alone, it goes from a haze you can wax out to a surface so far gone it needs wet-sanding, and eventually to gelcoat that can't be saved.

The timeline nobody tells you

The whole game is simple: keep a sacrificial layer (wax or ceramic) between Florida and your gelcoat, and rinse the salt off before it bakes in. Everything else is detail.

Wax vs. ceramic, honestly

Carnauba/polymer wax is the classic: warm shine, cheap, but 8–12 weeks of real protection in Florida sun — which is why quarterly waxing is the minimum serious schedule here. Ceramic coatings bond to the gelcoat and last 2–3 years, bead harder, and make every wash faster and gentler. They cost more up front and the prep has to be perfect, but per year of protection they usually win for boats that live in the water.

What a protection routine looks like

Why this matters at resale

Surveyors and buyers read gelcoat like a medical chart — chalky topsides say "deferred maintenance everywhere." A documented care history with photos does the opposite: it's the difference between a boat that sells in a week at asking and one that sits all season getting low-balled.
