The oil just wipes on sort of like furniture polish with a clean lint-free cloth. Let it dry between coats. Three-four coats a day (if I remember the drying time right) for about three days should build a film that's tough yet thin. If the neck is detached from the body it's fine to buff with 0000 steel wool. I use it all the time for frets and fingerboards even if the body is attached, but I take the time to tape off the pickups. The synthetic pads are obviously safer, but are more expensive, and its hard to find the fine (yellow) grade. The wax is like polishing your shoes. Apply a thin coat. let it dry for a few minutes and then buff until your are falls off.
