Sanding the boat
Sanding is an important step in the process of repainting a fiberglass drift boat with Easypoxy paint. It helps create a smooth and even surface for the new paint to adhere to and ensures a long-lasting finish. Here is a step-by-step guide to sanding your fiberglass drift boat:
Start by thoroughly cleaning the boat to remove any dirt, debris, or salt deposits, especially if the boat has been in saltwater. Use a high-pressure hose, rags, and a scraper if necessary. Rinse the boat thoroughly and ensure that there is no soap residue left on the surface.
Once the boat is clean and dry, inspect the surface for any chipped paint, gel coat, or cracks. Use 80-grit sandpaper to sand the entire surface of the boat, including the hull and deck areas. This step will help remove any remaining old paint, smooth out the surface, and create a uniform texture. It is important to sand in the direction of the grain of the fiberglass to avoid scratching or damaging the surface.
If your boat has areas with exposed epoxy, you can use a more aggressive approach. Start with 40-grit sandpaper to rough up the fiberglass surface. For the epoxy areas, switch to 36-grit sandpaper and apply more pressure during sanding. This will ensure that the new paint will adhere properly to the epoxy.
After sanding the entire boat, it is a good idea to apply a primer. Although it is not necessary for fiberglass boats, a primer will improve paint adhesion and provide a better finish. Choose a primer that is compatible with the Easypoxy paint you plan to use. Apply one layer of primer and allow it to dry according to the manufacturer's instructions.
Before applying the final coat of paint, use a finer grit sandpaper, such as 300-grit, to lightly sand the primed surface. This step will help create an even smoother surface and improve the adhesion of the topcoat. Make sure to sand lightly and evenly across the surface to avoid creating any noticeable scratches.
By following these steps, you will effectively sand your fiberglass drift boat, preparing it for a fresh coat of Easypoxy paint. Remember to take your time, work in a well-ventilated area, and wear the appropriate safety gear, including a respirator and protective eyewear, during the sanding process.

Choosing the right paint
Firstly, it is important to understand that paint for boats is different from the paint used for other surfaces, such as houses or cars. The paint you choose should be specifically designed for fibreglass boats and compatible with the previous coating or gel coat. If your boat has a gel coat finish, it is essential to know that gel coats are not waterproof. They absorb a small amount of water to prevent cracking. Therefore, if you plan to use a latex paint, you don't need to completely dry and seal the gel coat. However, if you prefer an epoxy-based paint, you must ensure that the gel coat is entirely dry and sealed before applying the new epoxy paint.
When it comes to specific paint recommendations, some popular options include West Marine's Pettit Easypoxy, Zolatone for the inside of the boat, and Awlgrip for the outside. These paints have been known to yield good results. Additionally, if you're looking for durability and gloss, a polyurethane finish is an excellent choice. Polyurethane application involves scuff sanding the fibreglass, wiping with a prep wipe and a tack cloth, and then applying an epoxy primer. Remember to use a forced-air breathing apparatus during the process, as the hardeners in polyurethanes contain cyanide.
Another highly recommended option is Durabak boat paint, which can save you time and money. This paint is specifically designed for fibreglass boats and can be easily applied by following the necessary preparation steps, such as cleaning and sanding the boat's surface. Additionally, if you're looking for a cost-effective solution, consider using latex swimming pool primer and pool top coat paint. This option is formulated with an anti-algae growth formula and is suitable for trailer boats.
Finally, it is worth noting that gel coating is also an option for refurbishing your fibreglass drift boat. While it can be more expensive, it will last longer and bond better to the existing fibreglass or gel coat. If you decide to go with a gel coat, you will need to strip all the paint and rough up the fibreglass surface before application.

Drying and sealing the paint
Before applying the Easypoxy paint, it is essential to prepare the surface properly. The surface must be clean and free of any dirt, loose paint, rust, oil, grease, wax, soap, or any other foreign matter. Wash painted areas with a solution of 2 cups of household ammonia per gallon of water, and then rinse thoroughly. For removing mildew, use household bleach instead of ammonia. Additionally, ensure that the surface is dry before painting. Avoid painting in the late afternoon when working outdoors, as dew may affect the wet film. In cooler temperatures, maintain air and surface temperatures at or above 50°F for at least 8 hours after application.
Easypoxy paint can be applied by brush, roller, or spray. For best results, stir the paint thoroughly before use. When using a brush or roller, apply the paint without thinning. However, in hot weather, consider adding 5-10% Pettit 120 Brushing Thinner to maintain a wet edge. For large, smooth surfaces, use a short nap roller and immediately level the paint with the tip of a brush. If using a conventional spray, thin the paint by 15-20% with Pettit 121 Spraying Thinner.
Apply thin, even coats of Easypoxy paint. It is recommended to apply one thin coat per day. After applying the first coat, let it dry overnight. Then, lightly sand the surface with 220-grit sandpaper before applying the second coat. Avoid applying multiple coats in a single day, as this can lead to improper drying and soft paint films. The drying time for the second coat can vary depending on temperature; allow 8 to 24 hours for curing. Ensure the paint is completely dry before launching the boat.
To seal the paint and achieve a high-gloss finish, consider using a product like Pettit EZ WoodSealer. Apply a coat of EZ WoodSealer to seal the porous grain. If you're working with epoxied wood, skip the sealer and move directly to priming. Apply one or two coats of a suitable primer, such as EZ Prime, and sand each coat with 80-120 grit sandpaper. Clean the surface between coats with Pettit 120 Thinner until a smooth base is achieved. Once the primed surface is clean and smooth, you can proceed with the first coat of Pettit Easypoxy.
