I have been building furniture as a hobby for about 25 years. I recently got a good deal on some Red Cedar and started building some Cedar Chests. I am having a hard time keeping the Red Cedar stable, it either warps or shrinks. The Cedar has air dried in a barn for 10 years and I have had it in my utility shed for abour 6 months. Is there a product I can get to stabilize the Red Cedar that will not stain it?
