I recently built a bookcase out of baltic birch plywood, and finished
it with one coat of 100% pure tung oil (from Lee Valley). I carefully
wiped it dry after appying the oil. The project looks beautiful but a
week later is still not dry. After several days I sanded with 000 steel
wool, which picked up bit of oil with a white waxy texture. However, a
piece of paper pressed on the shelves still absorbs oil. I really would
rather not wait a month (or whatever it will take) for the oil to
completely cure. Any advice?
