Take a knife blade point and lay it on it's side. Place it on one of the flat surfaces on the inside/inletting of the stock.
Press down with some strength and drag the blade backwards so as NOT to cut into the wood. But instead dragging the blade across the surface will lightly compress & burnish the small area.
If there's oil in the wood, that compressed area will immediately look wet. That's the oil in the wood. You can even soak up a bit with a slip of newsprint,, it's usually that 'wet'.
There will be no doubt when you see it.
Slather on another coating of the whiting powder.
I use plain alcohol instead of acetone to make up the paste.
Using acetone doesn't draw any more oil out of the wood than alcohol does. Acetone evaporates in 10seconds or so anyway.
Alcohol evaporates more slowly so you can brush the stuff in a little more briskly if that matters. It's cheaper,,if that matters.
Do the outside and down in the inletting.
Let the coating set undisturbed for a couple weeks.. at least.
Longer is better.
The tightly clinging shell of whiting hard set against the wood surface is what is needed to draw out the oil.
Hang it somewhere and forget about it. Let it do it's thing.
