Hi all,

Just looking for advice on repairing a Starboard Carbon Pro. It has some dings (see photos below). Firstly, does it even need repair? If so whats the best way to go about it?

Thanks!

Since Starboard claims on his website that the PVC sandwich foam deck is wrapped around the rails, you do not need repairs if the dings are on the deck or the rails. The PVC foam under the outer glass layer that you see in the top pic is waterproof.

However, you should dry and repair immediately with a proper repair (with glass or carbon cloth) any ding on the hull as the balsa there will soak up water and rot.

For these cosmetic small dings, you can use some quality 2-components marine epoxy putty, or solarez, or epoxy resin + microspheres. I tend to use solarez, it is so practical, with a cheap UV lamp you can make repairs at any time of the day and be back on the water instantly.

Whatever you do, the trick is to lightly sand any surface that the resin will touch, and cure under pressure under a tightly wrapped transparent stretchable tape (e.g: PVC). And sculpt the hardened repair afterwards with a good cutter knife to make it flush with the rest of the board before sanding (sanding a repair to be flush with the rest of the paint without damaging it is tricky). Try to keep a resin sample somewhere, and as soon as it doesn't stick to the finger anymore, it is time to cut the resin: it will be hard enough to stay in place, but soft enough to be cut easily. But you should wait some more to harden to sand it properly.

For the small paint chips in the bottom pic, a nail polish of an approximate color, or a touch-up auto paint pen + UV varnish.

The "brushed carbon" look of the top pic is obtained by spraying a light veil of white paint on a black surface, and sanding it lightly. For the repairs on these kind of paints I thus add black pigment in my resin, and spray paint some white, sand, and spray varnish. Or you can use resin + microspheres, with a tiny drop of black pigment to get a grey tint matching the general color for small repairs, and put the rest of the resin to the freezer for stopping its curing, so you can re-use it months later for other small paint chips.
