In my experience, for a more permanent repair, use a two part epoxy resin. Especially for an edge repair, epoxy works well and is durable. Any five minute epoxy two part resin from the hardware store works well. Make a "form" out of scotch tape, pour the resin on, and let it cure. Then sand to the correct shape. A dremel tool works well.
