How To Wax a Boat

Your boat’s fiberglass gelcoat will maintain its high gloss for a long time if you keep it clean, waxed and stored out of the sun. If the surface has started to discolor or dull, or if the gelcoat has been subjected to a lot of wear and tear, you’ll need to learn how to buff a boat. Although the process is basically simple, and not much different from buffing a car, every boat owner has a unique take on it. This article explains the basic steps in buffing a boat.

Position the boat on the trailer securely. Boats should be waxed out of the water, secured on the trailer, preferably parked on a flat, even surface. Because you'll be spraying products and moving all around the boat, you'll probably not want to have the trailer attached to your car, either.

• Depending on the style of your boat, you'll probably want to put the cover on before you get started waxing and cleaning the boat. To keep the interior safe, keep the cover on.

Clean the old wax from the surface. Use rags soaked with toluene or another dewaxing solvent to remove traces of old wax, which can keep polish and rubbing compounds from working evenly across the surface of the boat.

• Sweep the rag in one direction, applying light pressure. It's not something you should usually have to scrub very hard to remove. Allow the solvent to evaporate before buffing.

Wash with a proper detergent. Finish washing the surface with a sponge and special boat soap or a mild solution of dishwashing detergent and warm water.

• If the surface of your boat is stained, it's sometimes common to use a small amount of bleach to disinfect and clean thoroughly. It's also sometimes common to use lacquer thinner, Varsol or a special degreaser to remove sticky adhesive spots or greasy buildup. Don't use bleach on untreated or unstained wooden boats.
• Rinse the boat thoroughly with clean water and allow to dry. You can use a squeegee to speed up the drying process, if necessary.

Consider using a polish or buffing compound. Both polish and buffing compound are abrasives, which restore the shine to your boat’s fiberglass gelcoat by removing imperfections, discolorations and scrapes in the surface, increasing the reflective shine.

• Choose polish if your boat only needs light refinishing. Go with a stronger rubbing compound if the surface is excessively pitted or chalky, signs that the surface needs a much more substantial cleaning.
• Be very careful when using a rubbing compound. Gelcoat is extremely thin and an aggressive compound can burn through it quickly, necessitating an expensive and time-consuming repair job

Begin at the transom and work toward the bow. Work in sections about 2 feet (0.610 meters) square to apply the rubbing compound or polish. Use a soft cloth if you’re working by hand, or fit the buffer with a foam polishing pad. Apply a circle of polish or buffing compound to the cloth or pad and rub it into the surface using a steady, even, circular motion. Buff until the surface becomes glassy looking. If you can see through the gelcoat, you’ve gone too far.

• Some purists swear by hand buffing, while others argue that using a tool saves your muscles and helps eliminate streaks and swirls. Choose a low-speed buffer, not a high-speed sander, for better control. Tools with an orbital motion are less likely to leave swirling streaks.
• If you’re using a buffer, start at the slowest speed. Touch the pad lightly to the surface before starting the buffer so the polish or compound doesn’t spray in all directions.

 

 

 

Choose an appropriate variety of boating wax. The variety of boating wax you use will vary, depending on the style and the surface of your boat's gelcoat. Keeping gelcoat coated with wax can help the gelcoat maintain its shine for a long time, offering a protective buffer between the coat and the water.

• Collinite 885 is a commonly used and recommended boating wax, used also in surfing and for other purposes.

Use the same motion as with applying the buffing compound. As with polishing and compounding, you can apply wax by hand or with an electric buffer. Use the same circular motion to avoid streaking.

• Different varieties of wax may come with specific directions, so defer to the product that you buy.

 

Exercise care around fittings and in tight spaces. Regardless of whether you use an electric buffer or a hand buffer, work by hand around non-removable fittings to keep the buffer from catching on or damaging them. Do the same in tight crevices.

• Remove fittings ahead of time if possible, keeping the screws with the fixtures closely, so you won't get confused later.

Allow the wax to dry. After a small amount of time, the wax should start to look somewhat hazy, which means you're ready for a second buffing. It's important to allow the wax enough time to set, so it'll be able to protect the gelcoat. This should only take 5-10 minutes in the sun. 

Buff the wax to a shine. Use a soft towel or terrycloth bonnet if you decide to use an electric polisher, or a clean hand buffer and work in circles. The shine should really start to pop as you buff away the cloudiness of the wax.
