Fiberglass boats are a great choice for boat owners due to their structural material, which is usually a special outer surface resin called gel coat. This resin gives the boat its colour and shine. However, over time, the gel coat can become dull and stained, and it can be hard to clean. This is where detailing comes in. Detailing a fiberglass boat involves a wash, wax, and interior cleaning. It is important to use the right products and techniques to avoid damaging the gel coat and to ensure a thorough clean.

What You'll Learn
Wash the boat with a detergent and water solution
To detail a fiberglass boat, one of the first steps is to wash the boat with a detergent and water solution. This is a crucial step to ensure the boat is clean and free of any contaminants before proceeding with further detailing steps such as waxing or polishing. Here are some detailed instructions to guide you through the process:
Firstly, prepare the detergent solution by mixing a cup of detergent with a gallon of warm water. Warm water is preferred as it will help to create a more effective cleaning solution. It is important to wear rubber gloves to protect your hands from the chemicals in the detergent.
Next, use a sponge to wash the boat's surface with the detergent solution. Make sure to cover all areas of the boat, including hard-to-reach places. If you notice any signs of mildew, add a cup of household bleach to your detergent solution to effectively remove it. For challenging stains, such as fish blood or waterline scum, you may need to apply a concentrated cleaner specifically formulated for fiberglass. These cleaners can be found at marine supply stores or online.
After washing the boat, thoroughly rinse the surface with clean water to remove any detergent residue. Pay close attention to thoroughly rinsing and removing any cleaning solution, especially if you used bleach or a concentrated cleaner. Once rinsed, allow the boat to air dry completely before proceeding to the next step.
It is important to note that detergents may not entirely remove oil and grease contaminants from the porous gelcoat surface. If you plan to apply wax or polish, it is crucial to ensure the surface is free of any grease. To address this, use a rag soaked in MEK (methyl ethyl ketone) or acetone to wipe down the entire surface. Be sure to wear thick rubber gloves during this process to protect your skin from these strong chemicals.
By following these steps, you will effectively wash your fiberglass boat with a detergent and water solution, preparing it for further detailing and restoring its clean and shiny appearance.

Use bleach to remove mildew
Bleach is a popular household chemical used to remove mildew from boats. However, it should be noted that bleach can damage the wax on your boat's hull, so it should be used with caution. If you do choose to use bleach, it is important to wear protective gear, such as an N95 particulate mask, rubber gloves, coveralls, and eyewear, to prevent the spores from harming your body.
To remove mildew with bleach, create a solution of one part bleach to four parts freshwater. You can also add 2/3 cup of TSP (Tri-Sodium Phosphate) and 1/3 cup of laundry detergent to the mixture. Apply the solution to the affected areas and scrub with a brush or toothbrush. For tougher stains on white synthetic cushions, soak the surface in a mixture of one teaspoon of ammonia, 1/4 cup of hydrogen peroxide, and 3/4 cup of distilled water. If you have coloured vinyl cushions, test the solution on a small area first to ensure it doesn't damage the fabric.
Another option is to use a commercial mildew remover, such as Star brite's Mildew Stain Remover, which is a bleach-based product offered in a 22-ounce trigger spray bottle. This allows you to direct the spray into hard-to-reach areas, such as under quarter berths or up into chain lockers. Spray Nine Cleaner is another highly-rated product that does not contain bleach. Remember to always use these products in a well-ventilated area and to dispose of any rags or runoff properly.
To prevent mildew from returning, it is important to ensure your boat is well-ventilated. Cowl-style vents can help circulate air below decks. You can also use mildew blockers, such as 3M's Marine Mildew Block, or dehumidifiers, such as those made by Star brite, DampRid, and MaryKate, which use calcium chloride crystals to remove moisture from the air.

Apply wax to protect the gel coat
Waxing is an important step in the detailing process of a fibreglass boat. The gel coat on a fibreglass boat is a special resin that protects the hull and gives it its colour and shine. Over time, the gel coat can become dull, discoloured, and porous, making the boat harder to clean and more susceptible to staining. Therefore, waxing the gel coat is essential to protect it and maintain the boat's resale value.
Before applying wax, it is crucial to clean the boat thoroughly. This includes removing any organic or mineral stains, such as bird droppings, aquatic secretions, or rust, using appropriate cleaning products. Pay special attention to difficult stains like fish blood and waterline scum, which may require a concentrated cleaner formulated for fibreglass. Always follow the instructions on the product labels and ensure the boat is in a well-ventilated area when using chemicals.
After cleaning, the gel coat must be prepared for waxing. This involves removing any oil and grease from the surface, as contaminants can interfere with the wax's effectiveness. Use a rag soaked in MEK or acetone, and wear thick rubber gloves to protect your skin. Once the surface is clean and dry, you can move on to the waxing process.
When selecting a wax product, you can choose from various options, such as Collinite, Rejex, or Meguiars Pure Boat Wax. Apply the wax according to the product instructions, using a circular motion and ensuring even coverage. An electric buffer can be used to make the process easier and more efficient, especially for larger boats.
Finally, use a clean microfiber towel to buff the boat and remove any excess wax. This will ensure a smooth and shiny finish. It is recommended to wax the gel coat once every 3 to 4 months to protect it from the sun and water, maintaining the boat's exterior in good condition.

Buff the gel coat to make it shiny
Buffing the gel coat is an important step in making your fiberglass boat shiny and new-looking. The gel coat is a special resin that protects the hull of a fiberglass boat and gives it its colour and shine. Over time, the gel coat can become dull, gloomy, and chalky, so it is important to take steps to restore its shine.
To buff the gel coat, you will need to start by cleaning the surface with a detergent and water solution. Be sure to protect your hands with rubber gloves. If there is mildew present, add a cup of household bleach to the cleaning solution. Rinse the surface thoroughly and let it dry.
Next, you will need to remove any oil and grease from the gel coat surface. Detergents often fail to remove these contaminants from the porous gel coat. Use a rag soaked in MEK or acetone to wipe down the entire surface, turning the rag often and replacing it when necessary. Again, protect your skin with thick rubber gloves.
Once the surface is clean and dry, you can begin the buffing process. Select a rubbing compound that is formulated for fiberglass and apply it to the surface. Use a circular motion until the surface turns glassy. Be careful not to rub in one place for too long, as the gel coat can become transparent.
After the surface has been compounded, it is time to polish. You can use a product like Meguiars Pure Boat Polish or 3M Finesse to give the gel coat the oils it needs to achieve a "wet" look. Finally, coat the surface with a wax like Collinite or Rejex to protect the gel coat and enhance its shine.
By following these steps, you can effectively buff the gel coat of your fiberglass boat to make it shiny and well-protected.

Polish the gel coat to give it a wet look
To detail a fibreglass boat, you must pay close attention to the gel coat. The gel coat is a thin layer of resin that is sprayed into a boat's mould during the initial construction. It has little structural value but serves to protect the hull and give it its colour and shine. Over time, the gel coat can become dull and chalky due to exposure to the elements.
To restore the gel coat to its original shine and give it a wet look, you must polish it. Polishing a gel coat is an abrasive process, similar to using extremely fine sandpaper. It removes the pitted surface rather than coating it. Here are the steps to polish the gel coat effectively:
- Start by cleaning the gel coat thoroughly. Use a detergent or a specialised cleaner for fibreglass to remove any dirt, grease, or mildew. Ensure the surface is completely free of contaminants before proceeding.
- If the gel coat is heavily oxidised or damaged, you may need to consider wet/dry sanding. This involves using sandpaper of varying grit sizes, starting with a lower grit and working your way up to a higher grit. However, this is a drastic measure for extreme cases, as it can remove too much of the gel coat.
- Choose a suitable polish or compound. Look for products with strong abrasives specifically formulated for fibreglass. Meguiars Pure Boat Polish and 3M Finesse are popular options.
- Apply the polish to a small area at a time, using a soft cloth or a rotary polisher. Rub with a circular motion until the surface becomes smooth and glassy. Work sparingly and focus on one spot at a time to avoid excessive abrasion.
- After polishing, you may want to apply a coat of wax. Wax adds an extra layer of protection and can enhance the gloss. Choose a marine wax designed to seal and protect the gel coat.
- Use a clean microfiber towel to buff the surface and remove any excess wax, chemicals, or dirt.
By following these steps, you can effectively polish the gel coat of your fibreglass boat, restoring its shine and giving it a desired wet look. Remember to work carefully and avoid using too much abrasion to prevent damaging the gel coat.
