Timber Framers Guild Forums General General Forum Questions Neutralizing pitch on a Fir step?

i was thinking shellac maybe too- orange shellac for the outdoors. (also an excellent finish in itself for wood canvas canoes) this oxidizes off though so some other finish on top would be needed once the knots and pitch pockets are sealed. (this is what makes orange shellac so nice for a canoe bottom- you can recoat as often as you like)
