About the Service

Gelcoat and paint restoration remove oxidation, dullness, staining, and surface defects from your boat’s exterior. Sun exposure, saltwater, and daily use break down both gelcoat and marine-grade paint over time. The process starts with a full decontamination wash to strip away buildup, scum, and embedded contaminants before any correction begins. From there, we use a multi-stage compounding and polishing system tailored to the surface type, leveling oxidation, correcting defects, and restoring clarity and gloss. This is not a quick buff. It’s controlled correction built for marine conditions.

Every boat is inspected under controlled lighting to determine whether we’re working on gelcoat or painted surfaces and to select the correct pads, compounds, and machines. All surrounding hardware, trim, and sensitive areas are taped off and protected before machine work starts. We remove swirls, shallow scratches, stubborn water spots, and heavy residue above the waterline. When needed, restoration can be performed dockside, even with the boat in the water, using equipment designed specifically for safe in-water correction.

HM’s marine technicians are fully insured, certified, and trusted by long-time boat owners and captains who value proper craftsmanship. With years of experience correcting both gelcoat and painted hulls, we use proven techniques, not shortcuts. The result is a clean, uniform finish that holds up in real marine environments and looks right from every angle.

HM Car and Boat Detailing LLC is hands down one of the best detailing companies I've worked with. They wash the yacht I captain every week and handle monthly details as well as teak work, including sanding, finishing, and ceiling, all done to perfection. Their team is always on time, their pricing is fair, and they consistently go above and beyond. Even when I've needed them last minute, they've shown up with a great attitude and delivered excellent results. You can tell they take pride in their work. Highly recommend them to anyone looking for reliable, professional, and high-quality detailing services for their boat or yacht.

I'm a Captain of ten years and worked on several boats. I've used several detailing companies in that time. I've had the pleasure of working with Harold and HM detailing for 5 of those years. They have never been late, always have been there at request no matter how late or inconvenient. Over the years they have consistently displayed pride in their work, honesty and care. I would strongly recommend them to any captain or owner of a vessel of any size.
