Can You Use Car Wax on a Fiberglass Boat

There are many different types of waxes on the market, each designed for a specific purpose. Car wax, for example, is designed to protect the paint and finish of your car. Fiberglass boat wax is designed specifically for use on fiberglass boats.

While you can technically use car wax on a fiberglass boat, it’s not the best option. Car wax isn’t as durable as fiberglass boat wax and it won’t provide the same level of protection.

  • Wet the boat with a hose and spray on a liberal amount of car wax
  • Rub the wax in with a clean, soft cloth in circular motions
  • Allow the wax to dry for 20-30 minutes before buffing it off with another clean, soft cloth
  • Repeat this process every few months to keep your boat’s fiberglass hull looking shiny and new!
