Nothing worse than a ding during an epic session or on a surf trip. Solarez Epoxy repair putty is a mixture of clear, high strength, fiber reinforced epoxy resin and a solar activated catalyst. There is no mixing required. Just use it right from the tube. It gels in 5 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 Epoxy UV cure kit comes with a waterproof capsule and 60 + 220 grit sanding pad.
