How do you refinish a fiberglass canoe?
The best way is to sand down the gelcoat finish back to the fibre glass. Mix up new gelcoat and spread over the fibreglass. You need to smooth off the gelcoat as even as possible to eliminate the need to sand down too much. If there are small patches left these can be filled in with a gelcoat mix and sanded down using wet and dry sandpaper.
You are working on a power boat repaired fiberglass bottom primered it with a urethane primer wanted to know how to prep primer for jellcoat paint procedure?

How do you gelcoat fiberglass?
Gelcoating fiberglass is a critical step in the process of creating a smooth, durable, and aesthetically pleasing surface on fiberglass-reinforced objects, such as boats, automotive parts, and fiberglass pools. Gelcoat is a type of resin specifically formulated to provide a glossy, protective finish to fiberglass surfaces. Here's a step-by-step guide on how to gelcoat fiberglass: Surface Preparation: Begin by thoroughly cleaning the fiberglass surface to remove any dirt, grease, wax, or other contaminants. Use a solvent-based cleaner or detergent and water, followed by rinsing and drying the surface completely. Sand the surface with fine-grit sandpaper (typically 320 to 400 grit) to create a rough texture for better adhesion of the gelcoat. Ensure to sand evenly and remove any gloss from the surface. Wipe down the sanded surface with a tack cloth to remove any dust particles or residues. Mixing Gelcoat: Wear appropriate personal protective equipment (PPE), including gloves and goggles, when handling gelcoat. Follow the manufacturer's instructions for mixing the gelcoat resin and catalyst (hardener) in the correct ratio. Typically, the ratio is specified as a percentage by weight or volume. Mix the gelcoat and catalyst thoroughly in a clean container using a stir stick or mechanical mixer. Ensure complete homogeneity of the mixture to achieve consistent curing. Application: Apply the mixed gelcoat to the prepared fiberglass surface using a spray gun, brush, or roller, depending on the size and complexity of the object. Work quickly but methodically to ensure even coverage and minimize the risk of streaks, drips, or bubbles. Apply multiple thin coats rather than a single thick coat for better control and to avoid sagging or running of the gelcoat. Pay attention to overlapping each pass slightly to achieve uniform coverage and thickness. Curing: Allow the gelcoat to cure according to the manufacturer's recommendations. Curing times can vary depending on factors such as temperature, humidity, and the type of catalyst used. Ensure the curing environment is free from dust, debris, and other contaminants that could mar the surface. Monitor the gelcoat during the curing process to ensure proper adhesion and the absence of any defects. Finishing: After the gelcoat has fully cured, inspect the surface for any imperfections such as air bubbles, pinholes, or unevenness. Sand the cured gelcoat surface lightly with fine-grit sandpaper (typically 600 to 1500 grit) to remove any imperfections and achieve a smooth finish. Polish the sanded surface using a compound and polishing pad to restore gloss and enhance the appearance of the gelcoat. By following these steps carefully and adhering to proper techniques and safety precautions, you can achieve a high-quality gelcoat finish on fiberglass surfaces, ensuring durability, protection, and aesthetic appeal.

Do you need to use a primer with polyurethane paint on fiberglass?
On raw fibreglass, epoxy primer is necessary. On gelcoat, polyurathane paint sticks well, provided the surface is well sanded and cleaned with acetone, but pinholes and cratering can be a problem, so where a high standard is required, priming the gelcoat with epoxy is recommended.
