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.
Acid Wash Cambridge
Acid wash Cambridge is a specialized gelcoat restoration technique that removes oxidation, watermarks, and embedded contaminants from your boat's hull, bringing back the shine and protecting your investment.
If you own a boat in Cambridge or the surrounding area, you understand how quickly weather, sun, and water can dull even the most beautiful gelcoat. Over time, oxidation builds up like a hazy film, making your boat look tired and neglected even though you care for it. Many boat owners in Cambridge face this exact frustration: they spend time and money maintaining their vessels, yet the hull loses its luster. Finding a reliable service provider who can restore that shine without damaging the underlying gelcoat is another challenge altogether.
GTHN Boat Polishing serves boat owners across Cambridge, Hamilton, Burlington, Niagara, and the Greater Toronto Area with mobile gelcoat restoration services. We bring professional-grade equipment and expertise directly to your marina, dock, or storage location, so you do not have to haul your boat or wait weeks for an appointment.
The Problem: Oxidation and Dull Gelcoat
Gelcoat is designed to protect your boat's fiberglass, but it is not immune to the elements. Sun exposure breaks down the protective resin layer, saltwater and minerals deposit on the surface, and regular use leaves swirl marks and light scratches. In Cambridge, where boats are exposed to seasonal weather changes and moisture, this degradation accelerates. The result is a hazy, chalky appearance that makes your boat look weathered, even if the hull is structurally sound.
This oxidation does more than hurt your boat's appearance. It signals neglect to potential buyers if you ever decide to sell, and it leaves the underlying gelcoat vulnerable to deeper damage. Many boat owners put off tackling this problem because they assume it requires expensive, time-consuming work or fear that an inexperienced service provider will cause scratches or gouges. The uncertainty keeps them from acting until the damage becomes more severe.
Our Approach: Multi-Stage Correction and Professional Technique
GTHN Boat Polishing addresses oxidation with a methodical, multi-stage correction process tailored to the severity of your boat's condition. We do not use a one-size-fits-all approach; instead, we assess your gelcoat and develop a plan specific to your boat's needs.
The process begins with a thorough assessment and decontamination of the hull. We then apply progressively finer abrasives and compounds, removing oxidation and restoring clarity to the gelcoat. This is where skill and experience matter: the angle of application, the pressure, the progression of grits, and knowing when to stop all determine whether your hull emerges glossy and protected or overworked and dull. GTHN technicians are trained in these techniques and understand the chemistry of marine gelcoat. Because each boat's condition varies, we use premium products and proven methods rather than shortcuts, so your boat's finish is restored safely and completely.
After correction, we often apply a ceramic boat coating to lock in the shine and provide ongoing protection against oxidation, UV damage, and water spots. This additional layer gives Cambridge boat owners months or even longer of maintained brilliance before the next service is needed. You can also add marine flooring installation or other detailing services to maximize your boat's condition and enjoyment.
The Result: Restored Shine and Protected Investment
When GTHN Boat Polishing completes an acid wash Cambridge job, boat owners see a dramatic difference. The gelcoat regains its depth and gloss, swirl marks vanish, and the hull looks new again. More importantly, your boat is better protected going forward. A properly restored and sealed gelcoat resists oxidation much longer than a neglected one, meaning you spend less time and money fighting the same battle.
Boat owners in Cambridge report that a professional restoration changes how they feel about their vessel. A boat that looked tired suddenly feels pride-worthy again. If you plan to sell, the investment in professional restoration often pays for itself in buyer perception and resale value. Even if you plan to keep your boat for years, the combination of restored appearance and protective coating creates peace of mind. Your boat stays looking better longer, and you avoid the stress of watching oxidation creep back in.

Frequently Asked Questions
What is the difference between an acid wash and regular boat polishing?
An acid wash is a multi-stage correction process that removes oxidation and embedded contaminants, while regular polishing maintains an already clean surface. Acid washing is deeper and more aggressive, using progressively finer compounds to restore clarity and gloss to dull or hazy gelcoat. It is the right choice when oxidation has built up significantly.
How much does gelcoat restoration cost in Cambridge?
The cost depends on your boat's size, the extent of oxidation, and whether you add ceramic coating or other services. GTHN Boat Polishing assesses your boat and provides transparent pricing based on the work required. Contact us with photos and details of your boat to receive a quote.
Will acid washing damage my boat's gelcoat?
When performed correctly by trained professionals, acid washing restores gelcoat without damage. GTHN Boat Polishing uses proper technique, progressive abrasives, and professional-grade equipment to remove oxidation safely. Poor technique from inexperienced providers can cause gouges or swirl marks, which is why choosing a reputable service matters.
How long does the restoration last after an acid wash in Cambridge?
A properly restored gelcoat resists oxidation much longer than a neglected surface. Adding a ceramic coating extends protection to several months or more, depending on your boat's exposure and maintenance. Regular rinsing and preventative care help maintain the finish between professional services.
Can GTHN Boat Polishing service my boat at my marina or dock?
Yes. GTHN Boat Polishing is a mobile service that operates across Cambridge, Hamilton, Burlington, Niagara, and the Greater Toronto Area. We come to your marina, private dock, or storage location to perform the work, so you do not have to transport your boat.

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!
