Restoring the SHINE of your boat

Step 1: Initial Wash

A decontamination wash is essential to start correcting the gelcoat by scrubbing/washing the boat to remove old waxes and dirt to prepare the surface for restoration.

Step 2: Oxidation Removal

If the boat has heavy oxidation, it will be wet sanded as needed, particularly if it leaves a chalky residue at first touch. This will be followed by compounding to reveal the glossy gelcoat underneath.

Step 3: Polishing

Polishing will eliminate any scratches or swirls left from compounding and provide a protective layer.

Step 4: Protection

Once compounded and polished, GTHN will apply a coat of wax, polymer sealant or ceramic coating to protect the finish.

Step 5: Maintenance

Routine maintenance is essential for preserving the gelcoat. Regularly washing the boat and reapplying protective sealants will help keep it looking its best.

St Catherines Waxing Polymer Sealant

Waxing and applying polymer sealant to your boat hull protects the gelcoat, locks in shine, and guards against UV damage and salt water exposure. GTHN Boat Polishing specializes in this essential maintenance across St. Catherines, Hamilton, Burlington, Niagara, and the Greater Toronto Area, bringing professional-grade products and proven techniques directly to your marina or dock.

The Problem: Your Boat's Finish Is Fading Fast

If you keep your boat in or near St. Catherines, you know what the water and weather do. Sun, salt spray, algae, and oxidation dull the gelcoat month by month. You might notice the shine is gone, the color looks chalky, or the surface feels rough to the touch. Regular rinsing helps, but it is not enough. Without proper protection, your boat loses its appeal, and when the time comes to sell or trade up, that dull finish costs you money.

Many boat owners put off this work because they think it means hauling the boat out, booking time at a facility, or paying for costly yard fees. That friction keeps vessels looking neglected even when owners care deeply about their investment.

How GTHN Approaches St. Catherines Waxing in Polymer Sealant

GTHN Boat Polishing arrives at your location with everything needed. There is no towing, no storage hassle, and no downtime waiting for a yard to fit you in. The team brings professional-grade waxes and marine-specific polymer sealants that bond to gelcoat and create a durable shield against the elements.

The process begins with thorough cleaning and decontamination to remove salt residue, algae, and oxidized material. Once the hull is prepped, GTHN applies polymer sealant in thin, even coats, working methodically across every section. This is not a quick spray job-it is hands-on, detail-oriented work that takes time because it has to. The result is a hard, clear barrier that reflects light and repels water and contaminants for months.

A quality polymer sealant applied correctly lasts two to three times longer than traditional wax alone, and protects against UV and salt damage that would otherwise degrade gelcoat color and surface integrity.

Because GTHN handles the work on your schedule at your location, you keep your boat accessible and avoid the stress of managing yard logistics yourself.

Real Results: Restored Shine and Protected Value

Boat owners who use GTHN's sealant service report that their vessels look noticeably brighter within days. The finish feels smooth, water beads and rolls off rather than pooling, and the color regains depth and clarity. More importantly, that protection holds. Owners return for maintenance annually or every 18 months-far less often than they would need to rewax with traditional products.

One St. Catherines boat owner brought in a sailboat with a hull that had oxidized over two seasons of inconsistent care. GTHN performed a multi-stage correction to remove the chalky layer, then applied a durable polymer sealant. Six months later, the hull still gleamed. That same owner now schedules maintenance before the season begins, knowing the protection keeps resale value intact and reduces the time spent on upkeep.

The transparency matters too. GTHN explains what your boat needs, walks you through options, and does not upsell unnecessary work. You know what you are paying for and why.
