How do you remove antifouling paint from fiberglass boat?

To remove antifouling paint from a fiberglass boat, start by using a chemical paint stripper specifically designed for marine use, following the manufacturer's instructions carefully. Apply the stripper to the painted areas and allow it to sit for the recommended time to soften the paint. Use a plastic scraper or a non-abrasive pad to gently remove the paint, being cautious not to damage the fiberglass surface. Finally, wash the area with water and mild soap to remove any residue and allow it to dry completely before applying new paint.
