Any woodworkers out there? I have a hand hewn beam I kept outside for a couple years as a firepit bench. I soaked it in a semitransparent Thompson's water seal. Now I want to make a fireplace mantel out of it for our family room. The color of the stain is awful and I want to change it to a more natural color...or somehow remove the stain altogether. Is it possible? The beam has hewn marks so I can't sand it.
