Quick verdict
If your fiberglass or gelcoat damage is limited to holes, chips, scratches, and deep cracks, the Fiberglass-Boat-Repair-Kit is the compact, lower-priced fix. If you're facing a larger white gelcoat project and need a full gallon of brush-on material, the Marine Coat One White Gelcoat Repair Kit is the more substantial choice with tinting pigments included.

Where each product wins
The Fiberglass-Boat-Repair-Kit wins when you need a low-cost way to patch a small damaged area. Its two-part resin and curing agent are meant for hole, chip, scratch, and crack repair, and the white, freestanding format makes it easy to carry to the boat. It's also the obvious pick if you don't want a large leftover quantity of gelcoat sitting in storage.
The Marine Coat One kit wins when your project is too big for a tiny repair pack. The gallon size gives you enough material to cover a much wider surface, and the six included tinting pigments let you adjust the white to a closer match. Because it's brush-on, it's built for applying a coat over an area rather than filling a single cavity.
Product notes
Fiberglass-Boat-Repair-Kit, Gel-Coat-Repair-Kit, Marine -Fiberglass-Repair-Kit f
This kit combines a resin and a curing agent, so you use the two parts together to create an epoxy filler. The description points it squarely at fixing holes, chips, scratches, and deep cracks in fiberglass boats, and the white color helps small blemishes blend into a white finish. It weighs 0.28 kg, which keeps it light enough to stow in a small locker or bring along to the dock. The limitation is scale: this is a freestanding repair kit intended for localized patches, not for coating a whole hull section. If your problem is a single chip or a crack, it gives you the material without the bulk of a gallon container.
Marine Coat One, White Gelcoat Repair Kit For Boat - (White With Wax, Gallon
This is a full gallon of white brush-on gelcoat with wax, so it's sized for bigger jobs that a small repair kit can't handle. The set includes six 1/4 oz tinting pigments-white, black, yellow, blue, red, and brown-so you can warm the white into off-white or beige tones to better match your boat. Marine Coat One also notes that it's veteran owned and that a portion of each purchase supports homeless veterans. The limitation is that applying a gallon of gelcoat is a larger project than mixing a small batch of repair filler. Choose it when you want enough material to refresh a wide white area and don't mind the higher price for a more complete resurfacing kit.
Final choice by use case
For a localized hole, chip, scratch, or crack, the Fiberglass-Boat-Repair-Kit at $15.74 is the practical, low-cost answer. For a broader white gelcoat repair job, the Marine Coat One White Gelcoat Repair Kit at $109.99 provides the volume, brush-on application, and tinting pigments you need to match your boat's finish.
