Three part "oil" is great for gunstock and furniture. I apply a thin coat to sanded ( at 220 0r 320 grit)or bare wood. Then using wet/dry 220 grit paper and sanding block I wet sand to oil with the grain. The object is to create a slurry. The wet slurry is the wiped cross grain with a clean cloth. The sanding block makes the rubbing easier. The objective is to force some of the slurry into the wood's pores. Let dry OVN and repeat next with w/d 320 grit and new clean cloth. Ditto on day 3 but with w/d 400. Unless the wood is very dry/old & porous that should do it. Apply any top coat you are used to using. I like Spar Urithane, semi-gloss.
