Matt,

You have urethane, we have ancient old growth redwood that is just plumb loaded with tannins. Peirce and I played around with it a bit yesterday afternoon, and it is just tough to get this 50+ yr. old redwood deck wood to look good enough in prep.

Will see in an hour or so, but looks like we will both be on our knees, belt sanding the snot out of the wood. 'Course that raises up the tannins right to the surface. But hitting the wood in a test area with Ready Seal #80 brightener after sanding seems to knock it down enough where the medium red redwood only formula looks like it should.
