So, thin layer of epoxy, light sanding, then glass... It does wonders on the paddles anyway. |

This problem can be almost completely eliminated by warming up the room, before you glass and allowing the temp to remain steady or drop very slowly as you glass the canoe and allow the first two layers of epoxy to cure. The problem is almost non-existent by the third coat. Some air bubbles will always form as the epoxy displaces the air trapped between the strips and in the wood fibers. They can be brushed out or touched with your finger as they form. As the layers of epoxy set-up, the bubbles will cease to form. since you have already experienced the air bubbles and the small craters they form after the epoxy has cured, you will need to fill them with a small drop of epoxy and allowed to cure, then sanded smooth if you want them to become completely invisible. They cannot generally be sanded out. tom |
