Ok, I agree we need to oil our timbers, my question is when in the construction process. I put up a small frame 3 days after oiling the timbers with Land Ark last summer. The oil looked beautiful, but all of the foot and hand prints and strap marks did not. I soon realized that you cannot sand these imperfections out after the timbers are oiled. So here is my question...is it a better idea to put the frame up first, then do touch up sanding and then oil? Maybe just oil rafters and timbers hard to get to before the raising? What do you professionals think?
