    Let me admit it...i'm a total nube when it comes to finishing a body with oil. However i'm considering getting a lightweight swamp ash warmoth body and giving it a tung oil finish. I've heard swamp ash can be quite open poor.

    Am i likely to need to do some work filling grain before oiling or can i just apply the oil straight on? Or does it really depend on the wood?

    Alternatively if i want the easiest body to finish am i better just going with an alder body which has more of a closed grain?

    If you want a glass finish you’ll likely want to fill the grain. I like a grainy finish so I do without.

    Whether or not it needs filling depends a great deal on the finished appearance you want. If your goal is a glossy finish then yes it will need filling of some sort; you'll never achieve a glossy finish unless you have a very smooth surface. If you are okay with a steam punk look of sorts, then filling isn't absolutely necessary. But remember the smoother the finished product is, the less dirt, oil, and odor it can trap.

    yes, after a glassy finish...maybe i'm better off with alder?
     
  5. If you want a glass smooth finish, ash will need to be filled. Alder is more “closed grain” and you can get by without a filler but a finish like tung oil, which takes a while to build up, is still going to be a bit of work. Definitely recommend wet sanding the oil in after a few coats to help the process along.

    I think Ken shows it in this video. If not, it’s in one of his. He’s using TruOil but the process is the same.
