Take a look at sikkens cetol products - pricey and do darken wood more than helmsman even with the natural color, but holds up much longer than polyurethane or oil type finishes in my experience. Sikkens also has a clear door and window finish that is supposed to be good. Have a can I've not tried yet - it's very pricy compared to helmsman.
