It didn't come from re-sawing, routing, planning, scraping or cutting. I did the same milling steps on two different pieces of the white oak.
With rain water, tap water and bottled water on one board there were no spots at all. On the second trouble board I got spots on all of the surfaces after all of the milling steps.
Your comment on re-sawing made me look back at the photos. When I saw the spots on the deep cut bevel for the panel I started thinking this isn't on the surface. I decided to book match the wood down the center and apply some bottle water. Tons of spots. I hand planed the spots to almost gone from the surface. More water more spots. Now I am not believing a sharp plane iron makes pin dots on the surface of the wood with the A2 steel it leaves behind. Maybe I'm being boneheaded here but it seems like a stretch.
My curiosity is peaked with the results: one board unsolvable the second board no spots from any milling and any type of water.
Its been fun to fool with it while I wait for shellac to dry but I'm coming to the sad conclusion: I don't know what is happening.
