When applying, use a spray bottle or a soft brush to coat the entire surface of the boat, including the hull, deck, and any compartments. Pay close attention to areas that are more susceptible to damage, such as seams, joints, and areas where the fiberglass has been repaired.

After applying the fluid, allow it to sit for a specified period, usually around 15-20 minutes. This duration allows the fluid to penetrate any potential leaks or damaged areas. During this time, the fluid will change color or become visible, indicating the presence of a leak. The fluid might turn a specific shade of blue, green, or even glow under UV light, making it easy to spot.

Once the designated time has passed, inspect the boat thoroughly. Look for any areas where the fluid has changed color or is visible. These spots will indicate the location of potential leaks or damage. It's important to note that the fluid might also reveal hidden damage, such as small holes or cracks, which could be a result of previous repairs or manufacturing defects.

Remember, this method is a powerful tool for identifying leaks and potential issues in your fiberglass boat. By following these steps and using the appropriate leak detection fluid, you can ensure that your boat is safe and ready for the water. Always choose non-toxic, water-soluble fluids to maintain the integrity of the fiberglass material and the environment.

Test Pressure: Gradually increase the boat's water pressure to simulate a leak

When performing a leak test on a fiberglass boat, it's crucial to simulate a realistic scenario to ensure the vessel's integrity. One critical aspect of this process is gradually increasing the boat's water pressure to mimic potential leak conditions. Here's a detailed guide on how to approach this step:
