What Local Boaters Are Saying

Trusted by boaters across Hamilton, Burlington, Niagara, Toronto & surrounding marinas.

Kevin D, Caledon

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

I had GTHN polish my boat. He did a fantastic job! Upfront and honest, and worked very hard. I highly recommend them!

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!

Why I Do This

I started GTHN to give boaters the confidence that their boat will always look its best. I take pride in every job,
treat every boat like it’s my own, and stand behind the results — always.
