Our Process

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.
Fort Erie Wet Sanding
Wet sanding in Fort Erie is a controlled abrasive process that removes oxidation, scratches, and chalky buildup from your boat's gelcoat surface, followed by polishing to restore a deep, protective shine. It's one of the most effective ways to bring aging fiberglass back to life without replacing the entire outer layer.
Fort Erie boat owners understand the challenge: lake water, salt spray, UV exposure, and seasonal storage take a visible toll. Your vessel may look dull, feel rough to the touch, or show white streaking across the hull. That degradation is oxidation, and it signals that your boat's protective barrier is breaking down. The good news is that professional wet sanding can reverse most of this damage and protect your investment for years to come.
GTHN Boat Polishing specializes in this work across the Golden Horseshoe, including Fort Erie and the surrounding communities. We bring the full restoration process directly to your boat, whether it's moored at your favorite marina or stored on land. No need to haul your vessel elsewhere.
How Does Wet Sanding Differ from Dry Sanding?
Wet sanding uses water as a lubricant while fine-grit sandpaper works across the gelcoat surface, whereas dry sanding relies on friction alone. The water serves three critical purposes: it keeps the surface cool, washes away grit and debris continuously, and allows the technician to see the work clearly as it progresses. This control is why wet sanding produces a more even, professional result with less risk of burning through the gelcoat or creating uneven patches.
Think of it like the difference between sanding wood with and without a damp cloth. The water lets you work steadily and see exactly what you're doing. Dry sanding on fiberglass often generates heat, which can soften the gelcoat unevenly and cause swirl marks that are hard to correct later.
GTHN Boat Polishing uses multi-stage wet sanding techniques, starting with coarser grits to remove oxidation and deep scratches, then progressing to finer grits for a smooth, uniform surface ready for polish and protection.
Why Does Your Fort Erie Boat Need Wet Sanding?
Your boat's gelcoat is its first and most important defense against water, sun, and chemicals. Over time, UV light breaks down the resin binders in the gelcoat, exposing pigment and creating that chalky, faded appearance. Oxidation doesn't just look bad; it also allows moisture to penetrate, which can lead to structural problems, delamination, and costly repairs down the line.
Fort Erie's waterfront location means your boat faces intense seasonal sun, humidity, and temperature swings. Even boats stored indoors deteriorate without regular protection. Wet sanding removes the compromised outer layer and exposes fresh, protected gelcoat beneath. After sanding, GTHN applies ceramic coatings or high-quality marine polish to seal in that restored finish and provide UV protection going forward.
The result: your boat looks restored, your resale value is preserved, and you've stopped oxidation before it becomes a structural issue.
What Does the Process Look Like?
Professional wet sanding is a methodical, multi-step process. GTHN Boat Polishing begins with a thorough inspection to assess the depth of oxidation and any damage requiring special attention. The hull and deck are then cleaned and prepped.
The technician then wet-sands the surface using progressive grits, typically moving from 1000 to 2000 grit and finer, depending on the boat's condition. Water runs continuously to cool the work, clear debris, and let the tech monitor progress. Between stages, the surface is rinsed and dried so the next grit can work effectively.
Once sanding is complete, the boat is thoroughly cleaned to remove all dust and residue. GTHN then applies marine-grade polish or ceramic coating to protect the newly restored gelcoat and bring out its natural luster. The entire process typically takes one to three days, depending on the boat's size and condition.
Because the work is mobile, GTHN comes to your location in Fort Erie, your marina, or wherever your boat is stored. You don't move the boat; we bring the expertise to you.
How Long Does the Restored Finish Last?
The longevity of a restored finish depends on aftercare and environmental exposure. Without protection, oxidation will begin again within months. This is why GTHN pairs wet sanding with ceramic coating or quality polish application. A ceramic coating can provide protection lasting 1-2 years or more with proper maintenance, while marine polish typically requires annual reapplication.
| Protection Method | Duration | Maintenance Level | Best For |
|---|---|---|---|
| Marine Polish Alone | 6-12 months | Annual reapplication | Boats in covered storage |
| Ceramic Coating | 12-24 months | Occasional touch-ups | Active cruising vessels |
| Ceramic + Maintenance Wash | 18-30+ months | Seasonal care | Premium protection, frequent use |
GTHN also offers maintenance wash services to help extend the life of your restored finish between full restorations. A maintenance wash removes salt, grime, and environmental contaminants without aggressive sanding, keeping your boat in top condition year-round.
If you own a boat in Fort Erie or the surrounding Golden Horseshoe region and your gelcoat is showing signs of oxidation, fading, or wear, professional wet sanding can restore it to like-new condition.

Frequently Asked Questions
Is wet sanding safe for my boat's fiberglass?
Yes, when performed by experienced technicians using proper technique and equipment. Wet sanding actually protects fiberglass by cooling the surface and controlling material removal. The water lubricant prevents heat buildup and burning. GTHN Boat Polishing uses proven multi-stage methods that remove only the damaged outer layer without affecting the structural integrity of your boat.
How much does wet sanding cost in Fort Erie?
Pricing depends on your boat's size, the extent of oxidation, and whether you want ceramic coating or polish applied after sanding. Larger vessels and deeper oxidation require more time and materials. GTHN provides transparent quotes based on an on-site assessment. Contact them directly to discuss your boat and receive an estimate tailored to your needs.
Can wet sanding remove deep scratches and gouges?
Multi-stage wet sanding can address light to moderate scratches and surface damage. Deep gouges or structural cracks may require repair before sanding. GTHN's technicians assess your boat thoroughly and can recommend whether sanding alone will restore your boat or if additional repair steps are needed first.
What should I do after my boat has been wet sanded?
After professional wet sanding and coating application, protect the restored finish by rinsing your boat regularly with fresh water to remove salt and grime, avoiding abrasive cleaners, and applying a maintenance wash seasonally. GTHN can recommend a care schedule based on how often you use your boat and where it's stored.

We are beyond happy with the work done on polishing the hull of our boat. Not only is the work amazing, but Neil went out of his way to get our boat ready on time for launching. Small touches like putting painters tape on the line separating the gel coat and bottom paint are appreciated. As is the extra time spent on trouble spots. Highly recommend GTHN Boat Polishing!
