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.

I couldn’t be happier with how the ceramic coating turned out on my boat! I was blown away and the boat looks awesome! The shine is incredible and I know it will last. GTHN did an amazing job! Highly recommended!

Jan P, Hamilton

Chris B, Hamilton

It’s hard to find reliable people in this industry, but Neil was one of them. Price was fair, work was awesome, communication throughout was above and beyond. I will use GTHN again and would highly recommend if you found them, you do the same.

Phong T, Kitchener

This was the first time I worked with Neil and the experience was great. He came out to do a couple of test spots before we settled into a quote and the rest of the scheduling was just as easy. The end result was fantastic.
Definitely recommended!!! 🙂

Diego M, Toronto

I’m amazed with the work that was done. I highly recommend it 100%
Fast and best ever results. Thanks Neil for your time and effort.

Steve B, Hamilton

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!

We Will Come To You!
