I have been building some Canoe and SUP paddles lately and have been finishing them with West Systems Epoxy (105 epoxy and 206 hardener) and then a final spray of Minwax Spar Urethane.  Turns out real nice and gives an incredibly durable finish.  
I am thinking of using this same technique on my "Trade bow".  Is there any reason why this would not work with a bow?  Will the Epoxy be flexible enough?
Thanks

				It will work.
			
			
			
				I have used West systems to finish wood bows and had good luck with it.  I have also added strips of 4 oz cloth to both bellies and backs and increased weight.  I like it left clear with the varnish to protect the epoxy so the wood grain can be seen.  I have also painted camo  over the glass before I varnish them with great results

				I wonder if this is any different than Thunderbird? Do you apply it by spraying it?

I just rub it in by hand and then use an old rag to wipe off any extra.  Wet sand with 220 reapply a second coat, wet sand again, and then a final spray with the Minwax

Here ya go.
The Canoe paddle is not complete yet.  I have glassed the blade and applied the first coat of West Systems.  Still need to complete the finish and add the grip.
Enjoy!

Yes it is it is a epoxy resin and like all epoxy resin I know of it us damaged by U V sun rays and must be covered by a varnish that protects the epoxy from the rays of the sun.  
The main purpose of the product is to use a form to build composite products from fiberglass cloth and the epoxy resin as a wetting and gluing agent.  It is also used to cover the hulls of canoes and boats with fiberglass.  The good part is it is flexible and will work well as a  bellies and back on bows and when finishes it is similar to the glass strips we use.
