STEP ONE – ACCESS THE DAMAGE

First-things-first, access the damage. If the scratch does not penetrate deep into the fiberglass, you’re in good shape. Usually, a simple wet-sand and buff can bring back the original glow of the gelcoat.

STEP TWO – SANDPAPER

If the scratch is a bit deeper, start off by dry sanding with 180-grit sandpaper. Once the scratch appears to be fading, gradually move to a 320-grit, followed by a 500-grit, and finally a 1000-grit sandpaper. When using 400-grit or higher, make sure to wet sand. As you’re working through the gelcoat, do not remove too much and always use clean sandpaper. Do not use a circular motion, but rather an X pattern. This X-pattern technique will keep the sanded area flat, avoiding any sort of dip in the hull or deck.

STEP THREE – BUFF AND ENJOY!

Once the scratch is gone, buff it out and use a synthetic wax to protect the finish. After completing all three steps, the scratch should be gone and you can enjoy your squeaky-clean boat once more!
