Wax is the best bet to keep a new boat’s gelcoat smooth, shiny and rich in color. But if you (or a previous owner) didn’t keep up with that waxing routine, the sun’s UV rays have likely begun to oxidize that gelcoat, resulting in a dull, even chalky appearance and a greater tendency to stain. Restore gelcoat’s luster with a fiberglass/gelcoat restoration product. Start with a wash to remove surface dirt. Use an acid-based stain remover to get rid of unsightly organic (bird droppings) or mineral (rust) stains, followed by a restorer and polish to bring back that familiar shine. Once those good looks are back, keep that renewed finish with a good coat of wax.
