1936 Pickup bed floor question

[nelsb01]

To answer your question about what to seal the boards under the metal floor......
Roy Nacewicz told me that the closest he found to the color that Ford used was Minwax Ebony wood finish.
Of course in a reproduction bed you can only get to the bottom of the boards, but if you are replacing the metal floor of the bed, you can then work on the top side.
Hope this helps.
