I have started building a moccasin 2 http://www.bandbyachtdesigns.com/mocci.htm canoe. I have got all the pieces cut and am about to order the epoxy and other things to finish. I would like to leave the boat unpainted just the wood showing. I almost never see this in Stitch and glue canoes but see it in kayaks. Why is this?

The plans call for just 2 inch glass tape at the seams. Would the boat benefit structurally from a full glass cloth? What kid of pliers should I use for twisting the wire, would linemans pliers be good?
