I have a Kevlar canoe with new ash gunwales I'm installing, and I would like to stain them darker to match the walnut decks, if my goal was to finish everything with something like a Watco, what could I use to stain them darker prior? I would prefer not to varnish them because I really don't like the finished look of varnish vs oil, but I could go this route if it's the best with a stain/finish process.
