Here I am after two coats of tung oil. I apply a coat with a rag. I rub it in not just wipe it on. Rub a dub dub. After it dries, the next day I use 0000 steel wool to remove the excess. Apply, repeat. I'm going to do 4 coats. Steel wooling in between coats allows the oil to penetrate the wood and seal it somewhat for protection from moisture. Obviously since it isn't a hard finish, technically it is not totally sealed from moisture, but it will be just fine. The wool takes off the top layer and leaves only wood with what has soaked in. After the last bit of wool hits it, it will feel nice and raw.
