Oh Boy
Greg, the first question is Do you know what type of paint it is? Some soft paints can come off rather easily while a hard paint such as polyurethane can be really tough. The first thing to try is a mild abrasive. Believe it or not start with toothpaste. If it is a soft paint it will probably take off the paint and not damage the gelcoat. Put the toothpaste on a high speed polisher or buffer with a sheepskin cover. Keep the surface moist (not wet) while doing it. If that doesn't work, try a rubbing compound. They usually come in different grits - fine, medium and coarse. Again using the buffing machine. There are also some strippers specifically for fiberglass surfaces but you need to be VERY careful since even some mild stripper will distort the gelcoat.I hope this helpsCharlie
