Boat Oxidation Removal: The Complete Guide to Restoring Gelcoat

Oxidation: The Most Common Gelcoat Problem

UV radiation attacks gelcoat at the molecular level, breaking polymer chains and releasing pigment particles. The result is a chalky, faded surface that looks years older than it is. Oxidation is entirely treatable at any stage and entirely preventable with proper UV protection.

Step-by-Step Removal

Restoration method depends on severity. Light oxidation responds to polish alone; moderate needs compounding first; severe cases may require wet sanding. Our complete gelcoat oxidation removal guide walks through assessment, product selection, and technique for every severity level. For a faster workflow, see our marina manager's approach to oxidized gelcoat.

DIY vs Professional Methods

Professional compounding costs $15-40 per linear foot. DIY approaches using quality products cost a fraction of that. Our DIY and professional methods comparison covers both approaches so you can decide based on severity and your comfort level.

Restoring Faded Fiberglass

When oxidation has progressed to visible fading, a multi-step restoration brings back the original finish. See our faded fiberglass restoration guide for the full process from assessment to final sealant.

Prevention After Restoration

Bare gelcoat re-oxidizes within weeks. Apply UV-protective sealant immediately after restoration. Our year-round oxidation prevention guide covers maintenance schedules calibrated to your UV exposure.

Oxidation on Other Materials

UV degradation also affects Hypalon tubes, aluminum hulls, and rubber accessories. Our Hypalon oxidation restoration guide covers inflatable tubes, while our aluminum oxidation removal guide addresses the distinct process for metal hulls.
