Nothing worse than a ding during an epic session or on a surf trip. Solarez repair putty is a mixture of clear, non-yellowing, high-strength, fiber-reinforced polyester resin and a solar-activated catalyst. There is no mixing required, just use it right from the tube. It gels in 30 seconds, curing in 3 minutes - but ONLY when exposed to sunlight.
Since these thing tend to freeze up long-term, we opted to go with the 0.5 oz option. This polyester UV cure kit comes with a waterproof capsule and 60 + 220 grit sanding pad.
DO NOT USE ON EPS / STYROFOAM
