Is it ok to use bondo for boats?

Yes, Bondo can be used for certain repairs on boats, particularly for filling small dents and scratches in fiberglass surfaces. However, it's important to note that Bondo is not specifically designed for marine applications, so it may not withstand prolonged exposure to water or harsh marine conditions. For more critical repairs or areas exposed to constant moisture, it's advisable to use marine-grade fillers designed specifically for boat repair. Always follow up with proper sealing and painting to ensure durability.
