i have made a kayak paddle from ash,cherry,butternut,walnut. the shaft is laminated and i am wondering whether i should fiberglass the shaft? OR just coat with epoxy?, OR simply coat with varnish?.

P.S. i have already glassed the blades. Surprisingly i enjoyed the paddle making process more than the S&G kayak process, probably because i was creating the contours to my liking.

appreciate any tried and true advice, Craig.
