Yeah, that's how I do it when I'm french polishing--the whole rolled up material inside a cloth charged with alcohol, shellac and oil routine. When I'm just wiping on shellac, I just flick some mineral oil right on the work surface. Both methods work fine for me; what I haven't tried is mixing methods, say, by french polishing but flicking the oil right on the surface.

On my last french polishing effort, I switched from olive oil to mineral oil and saw improved results. I suspect that (as is pretty common in the olive oil industry these days) my olive oil was not pure olive oil, but had been adulterated with some other type of vegetable oil. I'll probably stick with mineral oil from here on out; cheap and effective is a winning combination, imo.
If you're gonna be one, be a Big Red One.
