Another vote for G-Flex. My old Werner Ikelos was pretty chipped on the blade ends. I sanded and cleaned the ends with acetone, then ran some painter's tape along the edges to make a dam. Next, I applied G-Flex along the edges.
After curing for a day, I removed the tape and sanded down the epoxy to form a new edge. It's been staying on there just fine, and protects the edge from new dings. Give it a try.
