I have recently started making a walnut gunstock but dont know how to finish it. I have been looking into just using danish oil but I dont know how to fill the grain. I have heard of people using the danish oil and sanding with the oil to let the oil/sanding dust slurry fill the grain. If this method was used how EXACTLY is it done and is it done before or after rubbing the multiple coats of oil for the actual finish? I want a gloss finish so will I need to use some fotten stone or pummice to polish the oil finish? If so how is this done.
