I had a real good suggestion from "Brian" on the Bear Mountain site. He suggested this:
1) Glue a scrap of cove strip ( having the same color and grain ) to the bead of the strip that needs some fat. I used a scrap about 15" long.
2) Bevel the scrap down to add about 1/16" to the bead of the full strip.
3) Plane and sand the new addition to taper out and achieve a nice bead.
4) Go forth to the canoe and fit the new strip in place.
This technique worked great and when on the canoe you can barely see where I added wood.
