just a phrase, you know how you need to lay down a few strips of glass at the bow and stern of a kayak where it hits the beach? It takes a lot of layers to get adequate thickness right where the wear is but that puts a lot of glass or other material wrapped around the sides where it's not exactly needed requiring a lot of fairing. I think a person could do a neater job with just a piece of 3/16" line of some sort but the dynel cord is easier to carve when the epoxy is green and I'm not sure that a rope would fuzz up too much.
